/**
|
||||
* Checks if `predicate` returns truthy for **any** element of `collection`.
|
||||
* The function returns as soon as it finds a passing value and does not iterate
|
||||
* over the entire collection. The predicate is bound to `thisArg` and invoked
|
||||
* with three arguments; (value, index|key, collection).
|
||||
*
|
||||
* If a property name is provided for `predicate` the created "_.property"
|
||||
* style callback returns the property value of the given element.
|
||||
*
|
||||
* If an object is provided for `predicate` the created "_.matches" style
|
||||
* callback returns `true` for elements that have the properties of the given
|
||||
* object, else `false`.
|
||||

||||
* @static
|
||||
* @memberOf _
|
||||
* @alias any
|
||||
* @category Collection
|
||||
* @param {Array|Object|string} collection The collection to iterate over.
|
||||
* @param {Function|Object|string} [predicate=_.identity] The function invoked
|
||||
* per iteration. If a property name or object is provided it is used to
|
||||
* create a "_.property" or "_.matches" style callback respectively.
|
||||
* @param {*} [thisArg] The `this` binding of `predicate`.
|
||||
* @returns {boolean} Returns `true` if any element passes the predicate check,
|
||||
* else `false`.
|
||||
* @example
|
||||
*
|
||||
* _.some([null, 0, 'yes', false], Boolean);
|
||||
* // => true
|
||||
*
|
||||
* var users = [
|
||||
* { 'user': 'barney', 'age': 36, 'active': false },
|
||||
* { 'user': 'fred', 'age': 40, 'active': true }
|
||||
* ];
|
||||
*
|
||||
* // using the "_.property" callback shorthand
|
||||
* _.some(users, 'active');
|
||||
* // => true
|
||||
*
|
||||
* // using the "_.matches" callback shorthand
|
||||
* _.some(users, { 'age': 1 });
|
||||
* // => false
