/**
* 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.
*
* @static
* @memberOf _
* @alias each
* @category Collection
* @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);
* }).value();
* // => logs each value from left to right and returns the array
*
* _.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)
