import zip from 'python-zip';

const a = [1, 3, 5];
const b = [2, 4, 6];

for (const [i, j] of zip(a, b)) {
    console.log(i, j); // => 1 2 then 3 4 then 5 6
}

Longest

import { zipLongest } from 'python-zip';

const a = [1, 3, 5, 7, 9];
const b = [2, 4, 6];

for (const [i, j] of zipLongest(a, b)) {
    console.log(i, j); // => 1 2 then 3 4 then 5 6 then 7 undefined then 9 undefined
}
