/**
 * This method is like `unzip` except that it accepts `iteratee` to specify
 * how regrouped values should be combined. The iteratee is invoked with the
 * elements of each group: (...group).
 *
 * @since 3.8.0
 * @category Array
 * @param {Array} array The array of grouped elements to process.
 * @param {Function} iteratee The function to combine
 *  regrouped values.
 * @returns {Array} Returns the new array of regrouped elements.
 * @example
 *
 * const zipped = zip([1, 2], [10, 20], [100, 200]);
 * // => [[1, 10, 100], [2, 20, 200]]
 *
 * unzipWith(zipped, add);
 * // => [3, 30, 300]
