11 * This method is like `_.zip` except that it accepts an array of grouped
12 * elements and creates an array regrouping the elements to their pre-zip
13 * configuration.
14 *
15 * @static
16 * @memberOf _
17 * @since 1.2.0
18 * @category Array
19 * @param {Array} array The array of grouped elements to process.
20 * @returns {Array} Returns the new array of regrouped elements.
21 * @example
22 *
23 * var zipped = _.zip(['a', 'b'], [1, 2], [true, false]);
24 * // => [['a', 1, true], ['b', 2, false]]
25 *
26 * _.unzip(zipped);
27 * // => [['a', 'b'], [1, 2], [true, false]]
