To zip two arrays in JavaScript, we use the map method.
For instance, we write
const a = [1, 2, 3];
const b = ["a", "b", "c"];
const c = a.map((e, i) => {
return [e, b[i]];
});
console.log(c);
to call a.map with a callback that returns an array with arrays of items in a and the items in b at the same position as the item in a.
