5 | * This method is like `_.zip` except that it accepts `iteratee` to specify
|
---|
6 | * how grouped values should be combined. The iteratee is invoked with the
|
---|
7 | * elements of each group: (...group).

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

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