Function zip

The zip() operator outputs tuples containing 1 element from the first and one element from the second iterator. The first iterator is leading, so when the first iterator is done, the output iterator is done. When the second iterator is 'shorter', the tuples will contain undefined as the second element.

Example

   pipe(
     itr8FromArray([ 1, 2, 3, 4 ]),
     zip(itr8FromArray([ 'a', 'b', 'c', 'd' ]), // => [ [1, 'a'], [2, 'b'], [3, 'c'], [4, 'd' ] ]
   );
