+/**
+ * This method is like `_.unzip` except that it accepts an iteratee to specify
+ * how regrouped values should be combined. The `iteratee` is bound to `thisArg`
+ * and invoked with four arguments: (accumulator, value, index, group).
+ *
+ * @static
+ * @memberOf _
+ * @category Array
+ * @param {Array} array The array of grouped elements to process.
+ * @param {Function} [iteratee] The function to combine regrouped values.
+ * @param {*} [thisArg] The `this` binding of `iteratee`.
+ * @returns {Array} Returns the new array of regrouped elements.
+ * @example
+ *
+ * var zipped = _.zip([1, 2], [10, 20], [100, 200]);
+ * // => [[1, 10, 100], [2, 20, 200]]
+ *
+ * _.unzipWith(zipped, _.add);
+ * // => [3, 30, 300]
