Run Underscore.js in noConflict mode, returning the _ variable to its

Add your own custom functions to the Underscore object, ensuring that
-they're correctly added to the OOP wrapper as well.

Generate a unique integer id (unique within the entire client session).
-Useful for temporary DOM ids.
             		                            
  var idCounter = 0;

By default, Underscore uses ERB-style template delimiters, change the
-following template settings to use alternative delimiters.
             		                            
  _.templateSettings = {
-    evaluate    : /<%([\s\S]+?)%>/g,
-    interpolate : /<%=([\s\S]+?)%>/g,
-    escape      : /<%-([\s\S]+?)%>/g
-  };
             		           
                               
                            
                                
               
When customizing templateSettings, if you don't want to define an
-interpolation, evaluation or escaping regex, we need one that is
-guaranteed not to match.
             		                            
  var noMatch = /.^/;
             		           
                               
                            
                                
               
Certain characters need to be escaped so that they can be put into a
-string literal.
             		                            
  var escapes = {
-    '\\': '\\',
-    "'": "'",

-    'u2028': '\u2028',

Within an interpolation, evaluation, or escaping, remove HTML escaping
-that had been previously added.
             		                            
  var unescape = function(code) {
-    return code.replace(unescaper, function(match, escape) {
-      return escapes[escape];
-    });

JavaScript micro-templating, similar to John Resig's implementation.
-Underscore templating handles arbitrary delimiters, preserves whitespace,
-and correctly escapes quotes within interpolated code.
             		                            
  _.template = function(text, data, settings) {

Compile the template source, taking care to escape characters that
-cannot be included in a string literal and then unescape them in code
-blocks.
             		                            
    var source = "__p+='" + text

-      })
-      .replace(settings.interpolate || noMatch, function(match, code) {
-        return "'+\n(" + unescape(code) + ")+\n'";
-      })
-      .replace(settings.evaluate || noMatch, function(match, code) {
-        return "';\n" + unescape(code) + "\n;__p+='";
-      }) + "';\n";
             		           
                               
                            
                                
               
If a variable is not specified, place data values in local scope.
             		                            
    if (!settings.variable) source = 'with(obj||{}){\n' + source + '}\n';

Provide the compiled function source as a convenience for build time
-precompilation.
             		                            
    template.source = 'function(' + (settings.variable || 'obj') + '){\n' +
-      source + '}';

Add a "chain" function, which will delegate to the wrapper.
             		                            
  _.chain = function(obj) {

The OOP Wrapper
             		                            
             		           
                               
                            
                                
               
If Underscore is called as a function, it returns a wrapped object that
-can be used OO-style. This wrapper holds altered versions of all the

Expose wrapper.prototype as _.prototype

A method to easily add functions to the OOP wrapper.

Add all of the Underscore functions to the wrapper object.

Add all accessor Array functions to the wrapper.

Extracts the result from a wrapped and chained object.

-      Underscore.js
-    

-
-    

-      Underscore is a
-      utility-belt library for JavaScript that provides a lot of the
-      functional programming support that you would expect in
-      Prototype.js
-      (or Ruby),
-      but without extending any of the built-in JavaScript objects. It's the
-      tie to go along with jQuery's tux,
-      and Backbone.js's suspenders.
-    

-
-    

-      Underscore provides 60-odd functions that support both the usual
-      functional suspects: map, select, invoke —
-      as well as more specialized helpers: function binding, javascript
-      templating, deep equality testing, and so on. It delegates to built-in
-      functions, if present, so modern browsers will use the
-      native implementations of forEach, map, reduce,
-      filter, every, some and indexOf.

Collection Functions (Arrays or Objects)

-
-      

-        each_.each(list, iterator, [context])
-        Alias: forEach
-        

-        Iterates over a list of elements, yielding each in turn to an iterator
-        function. The iterator is bound to the context object, if one is
-        passed. Each invocation of iterator is called with three arguments:
-        (element, index, list). If list is a JavaScript object, iterator's
-        arguments will be (value, key, list). Delegates to the native
-        forEach function if it exists.
-      

-      
-_.each([1, 2, 3], function(num){ alert(num); });
-=> alerts each number in turn...
-_.each({one : 1, two : 2, three : 3}, function(num, key){ alert(num); });
-=> alerts each number in turn...

-
-      

-        map_.map(list, iterator, [context])
-        Alias: collect
-        

-        Produces a new array of values by mapping each value in list
-        through a transformation function (iterator). If the native map method
-        exists, it will be used instead. If list is a JavaScript object,
-        iterator's arguments will be (value, key, list).
-      

-      
-_.map([1, 2, 3], function(num){ return num * 3; });
-=> [3, 6, 9]
-_.map({one : 1, two : 2, three : 3}, function(num, key){ return num * 3; });
-=> [3, 6, 9]

-
-      

-        reduce_.reduce(list, iterator, memo, [context])
-        Aliases: inject, foldl
-        

-        Also known as inject and foldl, reduce boils down a
-        list of values into a single value. Memo is the initial state
-        of the reduction, and each successive step of it should be returned by
-        iterator.
-      

-      
-var sum = _.reduce([1, 2, 3], function(memo, num){ return memo + num; }, 0);
-=> 6
-

-
-      

-        reduceRight_.reduceRight(list, iterator, memo, [context])
-        Alias: foldr
-        

-        The right-associative version of reduce. Delegates to the
-        JavaScript 1.8 version of reduceRight, if it exists. Foldr
-        is not as useful in JavaScript as it would be in a language with lazy
-        evaluation.
-      

-      
-var list = [[0, 1], [2, 3], [4, 5]];
-var flat = _.reduceRight(list, function(a, b) { return a.concat(b); }, []);
-=> [4, 5, 2, 3, 0, 1]
-

-
-      

-        find_.find(list, iterator, [context])
-        Alias: detect
-        

-        Looks through each value in the list, returning the first one that
-        passes a truth test (iterator). The function returns as
-        soon as it finds an acceptable element, and doesn't traverse the
-        entire list.
-      

-      
-var even = _.find([1, 2, 3, 4, 5, 6], function(num){ return num % 2 == 0; });
-=> 2
-

-
-      

-        filter_.filter(list, iterator, [context])
-        Alias: select
-        

-        Looks through each value in the list, returning an array of all
-        the values that pass a truth test (iterator). Delegates to the
-        native filter method, if it exists.
-      

-      
-var evens = _.filter([1, 2, 3, 4, 5, 6], function(num){ return num % 2 == 0; });
-=> [2, 4, 6]
-

-
-      

-        reject_.reject(list, iterator, [context])
-        

-        Returns the values in list without the elements that the truth
-        test (iterator) passes. The opposite of filter.
-      

-      
-var odds = _.reject([1, 2, 3, 4, 5, 6], function(num){ return num % 2 == 0; });
-=> [1, 3, 5]
-

-
-      

-        all_.all(list, iterator, [context])
-        Alias: every
-        

-        Returns true if all of the values in the list pass the iterator
-        truth test. Delegates to the native method every, if present.
-      

-      
-_.all([true, 1, null, 'yes'], _.identity);
-=> false
-

-
-      

-        any_.any(list, [iterator], [context])
-        Alias: some
-        

-        Returns true if any of the values in the list pass the
-        iterator truth test. Short-circuits and stops traversing the list
-        if a true element is found. Delegates to the native method some,
-        if present.
-      

-      
-_.any([null, 0, 'yes', false]);
-=> true
-

-
-      

-        include_.include(list, value)
-        Alias: contains
-        

-        Returns true if the value is present in the list, using
-        === to test equality. Uses indexOf internally, if list
-        is an Array.
-      

-      
-_.include([1, 2, 3], 3);
-=> true
-

-
-      

-        invoke_.invoke(list, methodName, [*arguments])
-        

-        Calls the method named by methodName on each value in the list.
-        Any extra arguments passed to invoke will be forwarded on to the
-        method invocation.
-      

-      
-_.invoke([[5, 1, 7], [3, 2, 1]], 'sort');
-=> [[1, 5, 7], [1, 2, 3]]
-

-
-      

-        pluck_.pluck(list, propertyName)
-        

-        A convenient version of what is perhaps the most common use-case for
-        map: extracting a list of property values.
-      

-      
-var stooges = [{name : 'moe', age : 40}, {name : 'larry', age : 50}, {name : 'curly', age : 60}];
-_.pluck(stooges, 'name');
-=> ["moe", "larry", "curly"]
-

-
-      

-        max_.max(list, [iterator], [context])
-        

-        Returns the maximum value in list. If iterator is passed,
-        it will be used on each value to generate the criterion by which the
-        value is ranked.
-      

-      
-var stooges = [{name : 'moe', age : 40}, {name : 'larry', age : 50}, {name : 'curly', age : 60}];
-_.max(stooges, function(stooge){ return stooge.age; });
-=> {name : 'curly', age : 60};
-

-
-      

-        min_.min(list, [iterator], [context])
-        

-        Returns the minimum value in list. If iterator is passed,
-        it will be used on each value to generate the criterion by which the
-        value is ranked.
-      

-      
-var numbers = [10, 5, 100, 2, 1000];
-_.min(numbers);
-=> 2
-

-
-      

-        sortBy_.sortBy(list, iterator, [context])
-        

-        Returns a sorted copy of list, ranked in ascending order by the
-        results of running each value through iterator. Iterator may
-        also be the string name of the property to sort by (eg. length).
-      

-      
-_.sortBy([1, 2, 3, 4, 5, 6], function(num){ return Math.sin(num); });
-=> [5, 4, 6, 3, 1, 2]
-

-
-      

-        groupBy_.groupBy(list, iterator)
-        

-        Splits a collection into sets, grouped by the result of running each
-        value through iterator. If iterator is a string instead of
-        a function, groups by the property named by iterator on each of
-        the values.
-      

-      
-_.groupBy([1.3, 2.1, 2.4], function(num){ return Math.floor(num); });
-=> {1: [1.3], 2: [2.1, 2.4]}
-
-_.groupBy(['one', 'two', 'three'], 'length');
-=> {3: ["one", "two"], 5: ["three"]}
-

-
-      

-        sortedIndex_.sortedIndex(list, value, [iterator])
-        

-        Uses a binary search to determine the index at which the value
-        should be inserted into the list in order to maintain the list's
-        sorted order. If an iterator is passed, it will be used to compute
-        the sort ranking of each value.
-      

-      
-_.sortedIndex([10, 20, 30, 40, 50], 35);
-=> 3
-

-
-      

-        shuffle_.shuffle(list)
-        

-        Returns a shuffled copy of the list, using a version of the
-        Fisher-Yates shuffle.
-      

-      
-_.shuffle([1, 2, 3, 4, 5, 6]);
-=> [4, 1, 6, 3, 5, 2]
-

-
-      

-        toArray_.toArray(list)
-        

-        Converts the list (anything that can be iterated over), into a
-        real Array. Useful for transmuting the arguments object.
-      

-      
-(function(){ return _.toArray(arguments).slice(1); })(1, 2, 3, 4);
-=> [2, 3, 4]
-

-
-      

-        size_.size(list)
-        

-        Return the number of values in the list.
-      

-      
-_.size({one : 1, two : 2, three : 3});
-=> 3
-

-
-      
Array Functions

-
-      

-        Note: All array functions will also work on the arguments object.
-      

-
-      

-        first_.first(array, [n])
-        Alias: head
-        

-        Returns the first element of an array. Passing n will
-        return the first n elements of the array.
-      

-      
-_.first([5, 4, 3, 2, 1]);
-=> 5
-

-
-      

-        initial_.initial(array, [n])
-        

-        Returns everything but the last entry of the array. Especially useful on
-        the arguments object. Pass n to exclude the last n elements
-        from the result.
-      

-      
-_.initial([5, 4, 3, 2, 1]);
-=> [5, 4, 3, 2]
-

-
-      

-        last_.last(array, [n])
-        

-        Returns the last element of an array. Passing n will return
-        the last n elements of the array.
-      

-      
-_.last([5, 4, 3, 2, 1]);
-=> 1
-

-
-      

-        rest_.rest(array, [index])
-        Alias: tail
-        

-        Returns the rest of the elements in an array. Pass an index
-        to return the values of the array from that index onward.
-      

-      
-_.rest([5, 4, 3, 2, 1]);
-=> [4, 3, 2, 1]
-

-
-      

-        compact_.compact(array)
-        

-        Returns a copy of the array with all falsy values removed.
-        In JavaScript, false, null, 0, "",
-        undefined and NaN are all falsy.
-      

-      
-_.compact([0, 1, false, 2, '', 3]);
-=> [1, 2, 3]
-

-
-      

-        flatten_.flatten(array, [shallow])
-        

-        Flattens a nested array (the nesting can be to any depth). If you
-        pass shallow, the array will only be flattened a single level.
-      

-      
-_.flatten([1, [2], [3, [[4]]]]);
-=> [1, 2, 3, 4];
-
-_.flatten([1, [2], [3, [[4]]]], true);
-=> [1, 2, 3, [[4]]];
-

-
-      

-        without_.without(array, [*values])
-        

-        Returns a copy of the array with all instances of the values
-        removed. === is used for the equality test.
-      

-      
-_.without([1, 2, 1, 0, 3, 1, 4], 0, 1);
-=> [2, 3, 4]
-

-
-      

-        union_.union(*arrays)
-        

-        Computes the union of the passed-in arrays: the list of unique items,
-        in order, that are present in one or more of the arrays.
-      

-      
-_.union([1, 2, 3], [101, 2, 1, 10], [2, 1]);
-=> [1, 2, 3, 101, 10]
-

-
-      

-        intersection_.intersection(*arrays)
-        

-        Computes the list of values that are the intersection of all the arrays.
-        Each value in the result is present in each of the arrays.
-      

-      
-_.intersection([1, 2, 3], [101, 2, 1, 10], [2, 1]);
-=> [1, 2]
-

-
-      

-        difference_.difference(array, *others)
-        

-        Similar to without, but returns the values from array that
-        are not present in the other arrays.
-      

-      
-_.difference([1, 2, 3, 4, 5], [5, 2, 10]);
-=> [1, 3, 4]
-

-
-      

-        uniq_.uniq(array, [isSorted], [iterator])
-        Alias: unique
-        

-        Produces a duplicate-free version of the array, using === to test
-        object equality. If you know in advance that the array is sorted,
-        passing true for isSorted will run a much faster algorithm.
-        If you want to compute unique items based on a transformation, pass an
-        iterator function.
-      

-      
-_.uniq([1, 2, 1, 3, 1, 4]);
-=> [1, 2, 3, 4]
-

-
-      

-        zip_.zip(*arrays)
-        

-        Merges together the values of each of the arrays with the
-        values at the corresponding position. Useful when you have separate
-        data sources that are coordinated through matching array indexes.
-        If you're working with a matrix of nested arrays, zip.apply
-        can transpose the matrix in a similar fashion.
-      

-      
-_.zip(['moe', 'larry', 'curly'], [30, 40, 50], [true, false, false]);
-=> [["moe", 30, true], ["larry", 40, false], ["curly", 50, false]]
-

-
-      

-        indexOf_.indexOf(array, value, [isSorted])
-        

-        Returns the index at which value can be found in the array,
-        or -1 if value is not present in the array. Uses the native
-        indexOf function unless it's missing. If you're working with a
-        large array, and you know that the array is already sorted, pass true
-        for isSorted to use a faster binary search.
-      

-      
-_.indexOf([1, 2, 3], 2);
-=> 1
-

-
-      

-        lastIndexOf_.lastIndexOf(array, value)
-        

-        Returns the index of the last occurrence of value in the array,
-        or -1 if value is not present. Uses the native lastIndexOf
-        function if possible.
-      

-      
-_.lastIndexOf([1, 2, 3, 1, 2, 3], 2);
-=> 4
-

-
-      

-        range_.range([start], stop, [step])
-        

-        A function to create flexibly-numbered lists of integers, handy for
-        each and map loops. start, if omitted, defaults
-        to 0; step defaults to 1. Returns a list of integers
-        from start to stop, incremented (or decremented) by step,
-        exclusive.
-      

-      
-_.range(10);
-=> [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
-_.range(1, 11);
-=> [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
-_.range(0, 30, 5);
-=> [0, 5, 10, 15, 20, 25]
-_.range(0, -10, -1);
-=> [0, -1, -2, -3, -4, -5, -6, -7, -8, -9]
-_.range(0);
-=> []
-

-
-      
Function (uh, ahem) Functions

-
-      

-        bind_.bind(function, object, [*arguments])
-        

-        Bind a function to an object, meaning that whenever
-        the function is called, the value of this will be the object.
-        Optionally, bind arguments to the function to pre-fill them,
-        also known as partial application.
-      

-      
-var func = function(greeting){ return greeting + ': ' + this.name };
-func = _.bind(func, {name : 'moe'}, 'hi');
-func();
-=> 'hi: moe'
-

-
-      

-        bindAll_.bindAll(object, [*methodNames])
-        

-        Binds a number of methods on the object, specified by
-        methodNames, to be run in the context of that object whenever they
-        are invoked. Very handy for binding functions that are going to be used
-        as event handlers, which would otherwise be invoked with a fairly useless
-        this. If no methodNames are provided, all of the object's
-        function properties will be bound to it.
-      

-      
-var buttonView = {
-  label   : 'underscore',
-  onClick : function(){ alert('clicked: ' + this.label); },
-  onHover : function(){ console.log('hovering: ' + this.label); }
-};
-_.bindAll(buttonView);
-jQuery('#underscore_button').bind('click', buttonView.onClick);
-=> When the button is clicked, this.label will have the correct value...
-

-
-      

-        memoize_.memoize(function, [hashFunction])
-        

-        Memoizes a given function by caching the computed result. Useful
-        for speeding up slow-running computations. If passed an optional
-        hashFunction, it will be used to compute the hash key for storing
-        the result, based on the arguments to the original function. The default
-        hashFunction just uses the first argument to the memoized function
-        as the key.
-      

-      
-var fibonacci = _.memoize(function(n) {
-  return n < 2 ? n : fibonacci(n - 1) + fibonacci(n - 2);
-});
-

-
-      

-        delay_.delay(function, wait, [*arguments])
-        

-        Much like setTimeout, invokes function after wait
-        milliseconds. If you pass the optional arguments, they will be
-        forwarded on to the function when it is invoked.
-      

-      
-var log = _.bind(console.log, console);
-_.delay(log, 1000, 'logged later');
-=> 'logged later' // Appears after one second.
-

-
-      

-        defer_.defer(function)
-        

-        Defers invoking the function until the current call stack has cleared,
-        similar to using setTimeout with a delay of 0. Useful for performing
-        expensive computations or HTML rendering in chunks without blocking the UI thread
-        from updating.
-      

-      
-_.defer(function(){ alert('deferred'); });
-// Returns from the function before the alert runs.
-

-
-      

-        throttle_.throttle(function, wait)
-        

-        Creates and returns a new, throttled version of the passed function,
-        that, when invoked repeatedly, will only actually call the original function
-        at most once per every wait
-        milliseconds. Useful for rate-limiting events that occur faster than you
-        can keep up with.
-      

-      
-var throttled = _.throttle(updatePosition, 100);
-$(window).scroll(throttled);
-

-
-      

-        debounce_.debounce(function, wait, [immediate])
-        

-        Creates and returns a new debounced version of the passed function that
-        will postpone its execution until after
-        wait milliseconds have elapsed since the last time it
-        was invoked. Useful for implementing behavior that should only happen
-        after the input has stopped arriving. For example: rendering a
-        preview of a Markdown comment, recalculating a layout after the window
-        has stopped being resized, and so on.
-      

-      
-      

-        Pass true for the immediate parameter to cause 
-        debounce to trigger the function on the leading intead of the 
-        trailing edge of the wait interval. Useful in circumstances like 
-        preventing accidental double-clicks on a "submit" button from firing a 
-        second time.
-      

-      
-      
-var lazyLayout = _.debounce(calculateLayout, 300);
-$(window).resize(lazyLayout);
-

-
-      

-        once_.once(function)
-        

-        Creates a version of the function that can only be called one time.
-        Repeated calls to the modified function will have no effect, returning
-        the value from the original call. Useful for initialization functions,
-        instead of having to set a boolean flag and then check it later.
-      

-      
-var initialize = _.once(createApplication);
-initialize();
-initialize();
-// Application is only created once.
-

-
-      

-        after_.after(count, function)
-        

-        Creates a version of the function that will only be run after first
-        being called count times. Useful for grouping asynchronous responses,
-        where you want to be sure that all the async calls have finished, before
-        proceeding.
-      

-      
-var renderNotes = _.after(notes.length, render);
-_.each(notes, function(note) {
-  note.asyncSave({success: renderNotes});
-});
-// renderNotes is run once, after all notes have saved.
-

-
-      

-        wrap_.wrap(function, wrapper)
-        

-        Wraps the first function inside of the wrapper function,
-        passing it as the first argument. This allows the wrapper to
-        execute code before and after the function runs, adjust the arguments,
-        and execute it conditionally.
-      

-      
-var hello = function(name) { return "hello: " + name; };
-hello = _.wrap(hello, function(func) {
-  return "before, " + func("moe") + ", after";
-});
-hello();
-=> 'before, hello: moe, after'
-

-
-      

-        compose_.compose(*functions)
-        

-        Returns the composition of a list of functions, where each function
-        consumes the return value of the function that follows. In math terms,
-        composing the functions f(), g(), and h() produces
-        f(g(h())).
-      

-      
-var greet    = function(name){ return "hi: " + name; };
-var exclaim  = function(statement){ return statement + "!"; };
-var welcome = _.compose(exclaim, greet);
-welcome('moe');
-=> 'hi: moe!'
-

-
-

-_.functions(_);
-=> ["all", "any", "bind", "bindAll", "clone", "compact", "compose" ...
-

-
-      

-        extend_.extend(destination, *sources)
-        

-        Copy all of the properties in the source objects over to the
-        destination object, and return the destination object.
-        It's in-order, so the last source will override properties of the same
-        name in previous arguments.
-      

-      
-_.extend({name : 'moe'}, {age : 50});
-=> {name : 'moe', age : 50}
-

-
-      

-        pick_.pick(object, *keys)
-        

-        Return a copy of the object, filtered to only have values for

-=> {name : 'moe', age : 50}
-

-
-      

-        defaults_.defaults(object, *defaults)
-        

-        Fill in missing properties in object with default values from the
-        defaults objects, and return the object. As soon as the
-        property is filled, further defaults will have no effect.
-      

-      
-var iceCream = {flavor : "chocolate"};
-_.defaults(iceCream, {flavor : "vanilla", sprinkles : "lots"});
-=> {flavor : "chocolate", sprinkles : "lots"}
-

-
-      

-        clone_.clone(object)
-        

-        Create a shallow-copied clone of the object. Any nested objects
-        or arrays will be copied by reference, not duplicated.
-      

-      
-_.clone({name : 'moe'});
-=> {name : 'moe'};
-

-
-      

-        tap_.tap(object, interceptor)
-        

-        Invokes interceptor with the object, and then returns object.
-        The primary purpose of this method is to "tap into" a method chain, in order to perform operations on intermediate results within the chain.
-      

-      
-_.chain([1,2,3,200])
-  .filter(function(num) { return num % 2 == 0; })
-  .tap(alert)
-  .map(function(num) { return num * num })
-  .value();
-=> // [2, 200] (alerted)
-=> [4, 40000]
-

-
-      

-        has_.has(object, key)
-        

-        Does the object contain the given key? Identical to
-        object.hasOwnProperty(key), but uses a safe reference to the
-        hasOwnProperty function, in case it's been
-        overridden accidentally.
-      

-      
-_.has({a: 1, b: 2, c: 3}, "b");
-=> true
-

-
-      

-        isEqual_.isEqual(object, other)
-        

-        Performs an optimized deep comparison between the two objects, to determine
-        if they should be considered equal.
-      

-      
-var moe   = {name : 'moe', luckyNumbers : [13, 27, 34]};
-var clone = {name : 'moe', luckyNumbers : [13, 27, 34]};
-moe == clone;
-=> false
-_.isEqual(moe, clone);
-=> true
-

-
-      

-        isEmpty_.isEmpty(object)
-

Utility Functions

-
-      

-        noConflict_.noConflict()
-        

-        Give control of the "_" variable back to its previous owner. Returns
-        a reference to the Underscore object.
-      

-      
-var underscore = _.noConflict();

-
-      

-        identity_.identity(value)
-        

-        Returns the same value that is used as the argument. In math:
-        f(x) = x

-        This function looks useless, but is used throughout Underscore as
-        a default iterator.
-      

-      
-var moe = {name : 'moe'};
-moe === _.identity(moe);
-=> true

-
-      

-        times_.times(n, iterator)
-        

-        Invokes the given iterator function n times.
-      

-      
-_(3).times(function(){ genie.grantWish(); });

-
-      

-        mixin_.mixin(object)
-        

-        Allows you to extend Underscore with your own utility functions. Pass
-        a hash of {name: function} definitions to have your functions
-        added to the Underscore object, as well as the OOP wrapper.
-      

-      
-_.mixin({
-  capitalize : function(string) {
-    return string.charAt(0).toUpperCase() + string.substring(1).toLowerCase();
-  }
-});
-_("fabio").capitalize();
-=> "Fabio"
-

-
-      

-        uniqueId_.uniqueId([prefix])
-        

-        Generate a globally-unique id for client-side models or DOM elements
-        that need one. If prefix is passed, the id will be appended to it.
-        Without prefix, returns an integer.
-      

-      
-_.uniqueId('contact_');
-=> 'contact_104'

-
-      

-        escape_.escape(string)
-        

-        Escapes a string for insertion into HTML, replacing
-        &, <, >, ", ', and / characters.
-      

-      
-_.escape('Curly, Larry & Moe');
-=> "Curly, Larry &amp; Moe"

-
-      

-        result_.result(object, property)
-        

-        If the value of the named property is a function then invoke it; otherwise, return it.
-      

-      
-var object = {cheese: 'crumpets', stuff: function(){ return 'nonsense'; }};
-_.result(object, 'cheese');
-=> "crumpets"
-_.result(object, 'stuff');
-=> "nonsense"

-
-      

-        template_.template(templateString, [data], [settings])
-        

-        Compiles JavaScript templates into functions that can be evaluated
-        for rendering. Useful for rendering complicated bits of HTML from JSON
-        data sources. Template functions can both interpolate variables, using
-        <%= … %>, as well as execute arbitrary JavaScript code, with
-        <% … %>. If you wish to interpolate a value, and have
-        it be HTML-escaped, use <%- … %> When you evaluate a template function, pass in a
-        data object that has properties corresponding to the template's free
-        variables. If you're writing a one-off, you can pass the data
-        object as the second parameter to template in order to render
-        immediately instead of returning a template function.  The settings argument
-        should be a hash containing any _.templateSettings that should be overriden.
-      

-
-      
-var compiled = _.template("hello: <%= name %>");
-compiled({name : 'moe'});
-=> "hello: moe"
-
-var list = "<% _.each(people, function(name) { %> <li><%= name %></li> <% }); %>";
-_.template(list, {people : ['moe', 'curly', 'larry']});
-=> "<li>moe</li><li>curly</li><li>larry</li>"
-
-var template = _.template("<b><%- value %></b>");
-template({value : '<script>'});
-=> "<b>&lt;script&gt;</b>"

-
-      

-        You can also use print from within JavaScript code.  This is
-        sometimes more convenient than using <%= ... %>.
-      

-
-      
-var compiled = _.template("<% print('Hello ' + epithet); %>");
-compiled({epithet: "stooge"});
-=> "Hello stooge."

-
-      

-        If ERB-style delimiters aren't your cup of tea, you can change Underscore's
-        template settings to use different symbols to set off interpolated code.
-        Define an interpolate regex to match expressions that should be
-        interpolated verbatim, an escape regex to match expressions that should
-        be inserted after being HTML escaped, and an evaluate regex to match
-        expressions that should be evaluated without insertion into the resulting
-        string. You may define or omit any combination of the three.
-        For example, to perform
-        Mustache.js
-        style templating:
-      

-
-      
-_.templateSettings = {
-  interpolate : /\{\{(.+?)\}\}/g
-};
-
-var template = _.template("Hello {{ name }}!");
-template({name : "Mustache"});
-=> "Hello Mustache!"

-
-      

-        By default, template places the values from your data in the local scope
-        via the with statement.  However, you can specify a single variable name
-        with the variable setting. This can significantly improve the speed
-        at which a template is able to render.
-      

-
-      
-_.template("<%= data.hasWith %>", {hasWith: 'no'}, {variable: 'data'});
-=> "no"

-
-      

-        Precompiling your templates can be a big help when debugging errors you can't
-        reproduce.  This is because precompiled templates can provide line numbers and
-        a stack trace, something that is not possible when compiling templates on the client.
-        The source property is available on the compiled template
-        function for easy precompilation.
-      

-
-      
<script>
-  JST.project = <%= _.template(jstText).source %>;
-</script>

-
-
-      
Chaining

-
-      

-        You can use Underscore in either an object-oriented or a functional style,
-        depending on your preference. The following two lines of code are
-        identical ways to double a list of numbers.
-      

-
-    
-_.map([1, 2, 3], function(n){ return n * 2; });
-_([1, 2, 3]).map(function(n){ return n * 2; });

-
-      

-        Calling chain on a wrapped object will cause all future method calls to
-        return wrapped objects as well. When you've finished the computation,
-        use value to retrieve the final value. Here's an example of chaining
-        together a map/flatten/reduce, in order to get the word count of
-        every word in a song.
-      

-
-
-var lyrics = [
-  {line : 1, words : "I'm a lumberjack and I'm okay"},
-  {line : 2, words : "I sleep all night and I work all day"},
-  {line : 3, words : "He's a lumberjack and he's okay"},
-  {line : 4, words : "He sleeps all night and he works all day"}
-];
-
-_.chain(lyrics)
-  .map(function(line) { return line.words.split(' '); })
-  .flatten()
-  .reduce(function(counts, word) {
-    counts[word] = (counts[word] || 0) + 1;
-    return counts;
-}, {}).value();
-
-=> {lumberjack : 2, all : 4, night : 2 ... }

-
-      

-        In addition, the
-        Array prototype's methods
-        are proxied through the chained Underscore object, so you can slip a
-        reverse or a push into your chain, and continue to
-        modify the array.
-      

-
-      

-        chain_.chain(obj)
-        

-        Returns a wrapped object. Calling methods on this object will continue
-        to return wrapped objects until value is used.
-      

-      
-var stooges = [{name : 'curly', age : 25}, {name : 'moe', age : 21}, {name : 'larry', age : 23}];
-var youngest = _.chain(stooges)
-  .sortBy(function(stooge){ return stooge.age; })
-  .map(function(stooge){ return stooge.name + ' is ' + stooge.age; })
-  .first()
-  .value();
-=> "moe is 21"
-

-
-      

-        value_(obj).value()
-        

-        Extracts the value of a wrapped object.
-      

-      
-_([1, 2, 3]).value();
-=> [1, 2, 3]
-

-        1.3.3 — April 10, 2012

-        
    
-          
  • 
-            Many improvements to _.template, which now provides the 
-            source of the template function as a property, for potentially
-            even more efficient pre-compilation on the server-side. You may now
-            also set the variable option when creating a template, 
-            which will cause your passed-in data to be made available under the 
-            variable you named, instead of using a with statement —
-            significantly improving the speed of rendering the template.
-          
    • 
-          
  • 
-            Added the pick function, which allows you to filter an 
-            object literal with a whitelist of allowed property names.
-          
    • 
-          
  • 
-            Added the result function, for convenience when working
-            with APIs that allow either functions or raw properties.
-          
    • 
-          
  • 
-            Added the isFinite function, because sometimes knowing that
-            a value is a number just ain't quite enough.
-          
    • 
-          
  • 
-            The sortBy function may now also be passed the string name
-            of a property to use as the sort order on each object.
-          
    • 
-          
  • 
-            Fixed uniq to work with sparse arrays.
-          
    • 
-          
  • 
-            The difference function now performs a shallow flatten
-            instead of a deep one when computing array differences.
-          
    • 
-          
  • 
-            The debounce function now takes an immediate
-            parameter, which will cause the callback to fire on the leading 
-            instead of the trailing edge.
-          
    •

-      

-        1.3.1 — Jan. 23, 2012

-        
    
-          
  • 
-            Added an _.has function, as a safer way to use hasOwnProperty.
-          
    • 
-          
  • 
-            Added _.collect as an alias for _.map. Smalltalkers, rejoice.
-          
    • 
-          
  • 
-            Reverted an old change so that _.extend will correctly copy
-            over keys with undefined values again.
-          
    • 
-          
  • 
-            Bugfix to stop escaping slashes within interpolations in _.template.
-          
    • 
-        

-      

-
-      

-        1.3.0 — Jan. 11, 2012

-        
    
-          
  • 
-            Removed AMD (RequireJS) support from Underscore. If you'd like to use
-            Underscore with RequireJS, you can load it as a normal script, wrap
-            or patch your copy, or download a forked version.
-

-        1.2.4 — Jan. 4, 2012

-        
    
-          
  • 
-            You now can (and probably should, as it's simpler) 
-            write _.chain(list) 
-            instead of _(list).chain().
-          
    • 
-          
  • 
-            Fix for escaped characters in Underscore templates, and for supporting
-            customizations of _.templateSettings that only define one or
-            two of the required regexes.
-          
    • 
-          
  • 
-            Fix for passing an array as the first argument to an _.wrap'd function.
-          
    • 
-          
  • 
-            Improved compatibility with ClojureScript, which adds a call
-            function to String.prototype.
-          
    •

-        1.2.3 — Dec. 7, 2011

-        
    
-          
  • 
-            Dynamic scope is now preserved for compiled _.template functions,
-            so you can use the value of this if you like.
-          
    • 
-          
  • 
-            Sparse array support of _.indexOf, _.lastIndexOf.
-          
    • 
-          
  • 
-            Both _.reduce and _.reduceRight can now be passed an
-            explicitly undefined value. (There's no reason why you'd
-            want to do this.)
-

-      

-        1.2.2 — Nov. 14, 2011

-        
    
-          
  • 
-            Continued tweaks to _.isEqual semantics. Now JS primitives are
-            considered equivalent to their wrapped versions, and arrays are compared
-            by their numeric properties only (#351).
-          
    • 
-          
  • 
-            _.escape no longer tries to be smart about not double-escaping
-            already-escaped HTML entities. Now it just escapes regardless (#350).
-          
    • 
-          
  • 
-            In _.template, you may now leave semicolons out of evaluated
-            statements if you wish: <% }) %> (#369).
-          
    • 
-          
  • 
-            _.after(callback, 0) will now trigger the callback immediately,
-            making "after" easier to use with asynchronous APIs (#366).
-          
    • 
-        

-      

-
-      

-        1.2.1 — Oct. 24, 2011

-        
    
-          
  • 
-            Several important bug fixes for _.isEqual, which should now
-            do better on mutated Arrays, and on non-Array objects with
-            length properties. (#329)
-          
    • 
-          
  • 
-            jrburke contributed Underscore exporting for AMD module loaders,
-            and tonylukasavage for Appcelerator Titanium.
-            (#335, #338)
-          
    • 
-          
  • 
-            You can now _.groupBy(list, 'property') as a shortcut for
-            grouping values by a particular common property.
-          
    • 
-          
  • 
-            _.throttle'd functions now fire immediately upon invocation,
-            and are rate-limited thereafter (#170, #266).
-          
    • 
-          
  • 
-            Most of the _.is[Type] checks no longer ducktype.
-          
    • 
-          
  • 
-            The _.bind function now also works on constructors, a-la
-            ES5 ... but you would never want to use _.bind on a
-            constructor function.
-          
    • 
-          
  • 
-            _.clone no longer wraps non-object types in Objects.
-          
    • 
-          
  • 
-            _.find and _.filter are now the preferred names for
-            _.detect and _.select.
-

-        1.2.0 — Oct. 5, 2011

-        
    
-          
  • 
-            The _.isEqual function now
-            supports true deep equality comparisons, with checks for cyclic structures,
-            thanks to Kit Cambridge.
-          
    • 
-          
  • 
-            Underscore templates now support HTML escaping interpolations, using
-            <%- ... %> syntax.
-          
    • 
-          
  • 
-            Ryan Tenney contributed _.shuffle, which uses a modified
-            Fisher-Yates to give you a shuffled copy of an array.
-          
    • 
-          
  • 
-            _.uniq can now be passed an optional iterator, to determine by
-            what criteria an object should be considered unique.
-          
    • 
-          
  • 
-            _.last now takes an optional argument which will return the last
-            N elements of the list.
-          
    • 
-          
  • 
-            A new _.initial function was added, as a mirror of _.rest,
-            which returns all the initial values of a list (except the last N).
-          
    • 
-        

-      

-
-      

-        1.1.7 — July 13, 2011

-        Added _.groupBy, which aggregates a collection into groups of like items.
-        Added _.union and _.difference, to complement the
-        (re-named) _.intersection.
-        Various improvements for support of sparse arrays.
-        _.toArray now returns a clone, if directly passed an array.
-        _.functions now also returns the names of functions that are present
-        in the prototype chain.
-      

-
-      

-        1.1.6 — April 18, 2011

-        Added _.after, which will return a function that only runs after
-        first being called a specified number of times.
-        _.invoke can now take a direct function reference.
-        _.every now requires an iterator function to be passed, which
-        mirrors the ECMA5 API.
-        _.extend no longer copies keys when the value is undefined.
-        _.bind now errors when trying to bind an undefined value.
-      

-
-      

-        1.1.5 — Mar 20, 2011

-        Added an _.defaults function, for use merging together JS objects
-        representing default options.
-        Added an _.once function, for manufacturing functions that should
-        only ever execute a single time.
-        _.bind now delegates to the native ECMAScript 5 version,
-        where available.
-        _.keys now throws an error when used on non-Object values, as in
-        ECMAScript 5.
-        Fixed a bug with _.keys when used over sparse arrays.
-      

-
-      

-        1.1.4 — Jan 9, 2011

-        Improved compliance with ES5's Array methods when passing null
-        as a value. _.wrap now correctly sets this for the
-        wrapped function. _.indexOf now takes an optional flag for
-        finding the insertion index in an array that is guaranteed to already
-        be sorted. Avoiding the use of .callee, to allow _.isArray
-        to work properly in ES5's strict mode.
-      

-
-      

-        1.1.3 — Dec 1, 2010

-        In CommonJS, Underscore may now be required with just: 

-        var _ = require("underscore").
-        Added _.throttle and _.debounce functions.
-        Removed _.breakLoop, in favor of an ECMA5-style un-break-able
-        each implementation — this removes the try/catch, and you'll now have
-        better stack traces for exceptions that are thrown within an Underscore iterator.
-        Improved the isType family of functions for better interoperability
-        with Internet Explorer host objects.
-        _.template now correctly escapes backslashes in templates.
-        Improved _.reduce compatibility with the ECMA5 version:
-        if you don't pass an initial value, the first item in the collection is used.
-        _.each no longer returns the iterated collection, for improved
-        consistency with ES5's forEach.
-      

-
-      

-        1.1.2

-        Fixed _.contains, which was mistakenly pointing at
-        _.intersect instead of _.include, like it should
-        have been. Added _.unique as an alias for _.uniq.
-      

-
-      

-        1.1.1

-        Improved the speed of _.template, and its handling of multiline
-        interpolations. Ryan Tenney contributed optimizations to many Underscore
-        functions. An annotated version of the source code is now available.
-      

-
-      

-        1.1.0

-        The method signature of _.reduce has been changed to match
-        the ECMAScript 5 signature, instead of the Ruby/Prototype.js version.
-        This is a backwards-incompatible change. _.template may now be
-        called with no arguments, and preserves whitespace. _.contains
-        is a new alias for _.include.
-      

-
-      

-        1.0.4

-        Andri Möll contributed the _.memoize
-        function, which can be used to speed up expensive repeated computations
-        by caching the results.
-      

-
-      

-        1.0.3

-        Patch that makes _.isEqual return false if any property
-        of the compared object has a NaN value. Technically the correct
-        thing to do, but of questionable semantics. Watch out for NaN comparisons.
-      

-
-      

-        1.0.2

-        Fixes _.isArguments in recent versions of Opera, which have
-        arguments objects as real Arrays.
-      

-
-      

-        1.0.1

-        Bugfix for _.isEqual, when comparing two objects with the same
-        number of undefined keys, but with different names.
-      

-
-      

-        1.0.0

-        Things have been stable for many months now, so Underscore is now
-        considered to be out of beta, at 1.0. Improvements since 0.6
-        include _.isBoolean, and the ability to have _.extend
-        take multiple source objects.
-      

-
-      

-        0.6.0

-        Major release. Incorporates a number of
-        Mile Frawley's refactors for
-        safer duck-typing on collection functions, and cleaner internals. A new
-        _.mixin method that allows you to extend Underscore with utility
-        functions of your own. Added _.times, which works the same as in
-        Ruby or Prototype.js. Native support for ECMAScript 5's Array.isArray,
-        and Object.keys.
-      

-
-      

-        0.5.8

-        Fixed Underscore's collection functions to work on
-        NodeLists and
-        HTMLCollections
-        once more, thanks to
-        Justin Tulloss.
-      

-
-      

-        0.5.7

-        A safer implementation of _.isArguments, and a
-        faster _.isNumber,
thanks to
-        Jed Schmidt.
-      

-
-      

-        0.5.6

-        Customizable delimiters for _.template, contributed by
-        Noah Sloan.
-      

-
-      

-        0.5.5

-        Fix for a bug in MobileSafari's OOP-wrapper, with the arguments object.
-      

-
-      

-        0.5.4

-        Fix for multiple single quotes within a template string for
-        _.template. See:
-        Rick Strahl's blog post.
-      

-
-      

-        0.5.2

-        New implementations of isArray, isDate, isFunction,
-        isNumber, isRegExp, and isString, thanks to
-        a suggestion from
-        Robert Kieffer.
-        Instead of doing Object#toString
-        comparisons, they now check for expected properties, which is less safe,
-        but more than an order of magnitude faster. Most other Underscore
-        functions saw minor speed improvements as a result.
-        Evgeniy Dolzhenko
-        contributed _.tap,
-        similar to Ruby 1.9's,
-        which is handy for injecting side effects (like logging) into chained calls.
-      

-
-      

-        0.5.1

-        Added an _.isArguments function. Lots of little safety checks
-        and optimizations contributed by
-        Noah Sloan and
-        Andri Möll.
-      

-
-      

-        0.5.0

-        [API Changes] _.bindAll now takes the context object as
-        its first parameter. If no method names are passed, all of the context
-        object's methods are bound to it, enabling chaining and easier binding.
-        _.functions now takes a single argument and returns the names
-        of its Function properties. Calling _.functions(_) will get you
-        the previous behavior.
-        Added _.isRegExp so that isEqual can now test for RegExp equality.
-        All of the "is" functions have been shrunk down into a single definition.
-        Karl Guertin contributed patches.
-      

-
-      

-        0.4.7

-        Added isDate, isNaN, and isNull, for completeness.
-        Optimizations for isEqual when checking equality between Arrays
-        or Dates. _.keys is now 25%–2X faster (depending on your
-        browser) which speeds up the functions that rely on it, such as _.each.
-      

-
-      

-        0.4.6

-        Added the range function, a port of the
-        Python
-        function of the same name, for generating flexibly-numbered lists
-        of integers. Original patch contributed by
-        Kirill Ishanov.
-      

-
-      

-        0.4.5

-        Added rest for Arrays and arguments objects, and aliased
-        first as head, and rest as tail,
-        thanks to Luke Sutton's patches.
-        Added tests ensuring that all Underscore Array functions also work on
-        arguments objects.
-      

-
-      

-        0.4.4

-        Added isString, and isNumber, for consistency. Fixed
-        _.isEqual(NaN, NaN) to return true (which is debatable).
-      

-
-      

-        0.4.3

-        Started using the native StopIteration object in browsers that support it.
-        Fixed Underscore setup for CommonJS environments.

-      

-        0.4.2

-        Renamed the unwrapping function to value, for clarity.
-      

-
-      

-        0.4.1

-        Chained Underscore objects now support the Array prototype methods, so
-        that you can perform the full range of operations on a wrapped array
-        without having to break your chain. Added a breakLoop method
-        to break in the middle of any Underscore iteration. Added an
-        isEmpty function that works on arrays and objects.
-      

-
-      

-        0.4.0

-        All Underscore functions can now be called in an object-oriented style,
-        like so: _([1, 2, 3]).map(...);. Original patch provided by
-        Marc-André Cournoyer.
-        Wrapped objects can be chained through multiple
-        method invocations. A functions method
-        was added, providing a sorted list of all the functions in Underscore.
-      

-
-      

-        0.3.3

-        Added the JavaScript 1.8 function reduceRight. Aliased it
-        as foldr, and aliased reduce as foldl.
-      

-
-      

-        0.3.2

-        Now runs on stock Rhino
-        interpreters with: load("underscore.js").
-        Added identity as a utility function.
-      

-
-      

-        0.3.1

-        All iterators are now passed in the original collection as their third
-        argument, the same as JavaScript 1.6's forEach. Iterating over
-        objects is now called with (value, key, collection), for details
-        see _.each.
-      

-
-      

-        0.3.0

-        Added Dmitry Baranovskiy's
-        comprehensive optimizations, merged in
-        Kris Kowal's patches to make Underscore
-        CommonJS and
-        Narwhal compliant.
-      

-
-      

-        0.2.0

-        Added compose and lastIndexOf, renamed inject to
-        reduce, added aliases for inject, filter,
-        every, some, and forEach.
-      

-
-      

-        0.1.1

-        Added noConflict, so that the "Underscore" object can be assigned to
-        other variables.
-      

-
-      

-        0.1.0

-        Initial release of Underscore.js.
