/** |
|
* 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). |
|
* |
|
* @static |
|
* @memberOf _ |
|
* @since 3.8.0 |
|
* @category Array |
|
* @param {...Array} [arrays] The arrays to process. |
|
* @param {Function} [iteratee=_.identity] The function to combine |
|
* grouped values. |
|
* @returns {Array} Returns the new array of grouped elements. |
|
* @example |
|
* |
|
* _.zipWith([1, 2], [10, 20], [100, 200], function(a, b, c) { |
|
* return a + b + c; |
|
* }); |
|
* // => [111, 222] |
