5 * This method is like `_.zip` except that it accepts `iteratee` to specify
6 * how grouped values should be combined. The iteratee is invoked with the
7 * elements of each group: (...group).
8 *
9 * @static
10 * @memberOf _
11 * @since 3.8.0
12 * @category Array
13 * @param {...Array} [arrays] The arrays to process.
14 * @param {Function} [iteratee=_.identity] The function to combine
15 * grouped values.
16 * @returns {Array} Returns the new array of grouped elements.
17 * @example
18 *
19 * _.zipWith([1, 2], [10, 20], [100, 200], function(a, b, c) {
20 * return a + b + c;
21 * });
22 * // => [111, 222]
