	/**
	* 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]
