/**
|

|
|
* 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). Iteratee 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`.
|
||
|
|
* @returns {Array|Object|string} Returns `collection`.
|

|

* @example
|
||
|
|
*
|
||
|
|
* _([1, 2]).forEach(function(n) {
|

* console.log(n);

|

|
|
* _.forEach({ 'a': 1, 'b': 2 }, function(n, key) {
|
||
|
|
* console.log(n, key);
|
||
|
|
* });
|
||
|
|
* // => logs each value-key pair and returns the object (iteration order is not guaranteed)
