/**

* Iterates over elements of `collection` invoking `iteratee` for each element.
|
||||
* The `iteratee` is bound to `thisArg` and invoked with three arguments;
|
||||
* (value, index|key, collection). Iterator functions may exit iteration early
|
||||
* by explicitly returning `false`.
|
||||
*
|
||||
* **Note:** As with other "Collections" methods, objects with a `length` property
|
||||
* are iterated like arrays. To avoid this behavior `_.forIn` or `_.forOwn`
|
||||
* may be used for object iteration.

|

* @param {Array|Object|string} collection The collection to iterate over.
|

* @param {Function} [iteratee=_.identity] The function invoked per iteration.
|

* @param {*} [thisArg] The `this` binding of `iteratee`.
|

*
|

* _([1, 2, 3]).forEach(function(n) { console.log(n); }).value();
|

*
|
||||
* _.forEach({ 'one': 1, 'two': 2, 'three': 3 }, function(n, key) { console.log(n, key); });
|

* // => logs each value-key pair and returns the object (iteration order is not guaranteed)
