/**
 * This method is like `zip` except that it accepts `iteratee` to specify
 * how grouped values should be combined. The iteratee is invoked with the
 * elements of each group: (...group).
 *
 * @since 3.8.0
 * @category Array
 * @param {...Array} [arrays] The arrays to process.
 * @param {Function} iteratee The function to combine
 *  grouped values.
 * @returns {Array} Returns the new array of grouped elements.
 * @example
 *
 * zipWith([1, 2], [10, 20], [100, 200], (a, b, c) => a + b + c);
 * // => [111, 222]
