+ * 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.

+ * @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, 3]).forEach(function(n) { console.log(n); });
+ * // => logs each value from left to right and returns the array
+ *
+ * _.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)
