+ * Iterates over elements of `collection` invoking `iteratee` for each element.
+ * The iteratee is 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 use `_.forIn` or `_.forOwn`
+ * for object iteration.
+ *

+ * @category Collection
+ * @param {Array|Object} collection The collection to iterate over.
+ * @param {Function} [iteratee=_.identity] The function invoked per iteration.
+ * @returns {Array|Object} Returns `collection`.
+ * @example
+ *
+ * _([1, 2]).forEach(function(value) {
+ * console.log(value);
+ * });
+ * // => logs `1` then `2`
+ *
+ * _.forEach({ 'a': 1, 'b': 2 }, function(value, key) {
+ * console.log(key);
+ * });
+ * // => logs 'a' then 'b' (iteration order is not guaranteed)
