/**

|
* 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).

|

|
* @param {...Array} [arrays] The arrays to process.
|

|
|
* @param {Function} [iteratee=_.identity] The function to combine

* grouped values.
