zip

Problem

You have two or more parallel arrays and need to combine them element-by-element into tuples.

Solution

Use zip(...arrays) to return an array of tuples, one per index position.

import { zip } from '@vielzeug/arsenal';

zip(['a', 'b', 'c'], [1, 2, 3]);
// [['a', 1], ['b', 2], ['c', 3]]

zip([1, 2], ['x', 'y'], [true, false]);
// [[1, 'x', true], [2, 'y', false]]

Pitfalls

• Output length is the length of the shortest input array — extra elements are dropped.
