How to zip multiple arrays in JavaScript

In this Article we will go through how to zip multiple arrays only using single line of code in JavaScript. This is a one-line JavaScript code snippet that uses one of the most popular ES6 features => Arrow Function.

Let's define this short function:

const zip = (...arr) => Array.from({ length: Math.max(...arr.map(a => a.length)) }, (_, i) => arr.map(a => a[i]));

#Example

zip(['a', 'b', 'c', 'd', 'e'], [1, 2, 3, 4, 5]);   // [['a', 1], ['b', 2], ['c', 3], ['d', 4], ['e', 5]]

/*
Does it look like a zipper?
        a 1
        b 2
       c   3
      d     4
     e       5
*/
