- * Iterates over elements of `collection` and invokes `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.

- * @param {Array|Object} collection The collection to iterate over.
- * @param {Function} [iteratee=_.identity] The function invoked per iteration.
- * @returns {Array|Object} Returns `collection`.

- * @example
- *
- * _.forEach([1, 2], function(value) {
