Sorting array by even and odd numbers

Question

Using javascript sort() method, I am trying to do sorting a list but sorting have in a group of even numbers and odd numbers.

The code which I tried is work

Answer 1

The short of the shortest:

n.sort(function(a, b) {
    return a % 2 - b % 2 || a - b;
});

To make it work with negative numbers we can add Math.abs():

n.sort(function(a, b) {
    return Math.abs(a % 2) - Math.abs(b % 2) || a - b;
});

Or even more compact variant using bitwise AND:

n.sort(function(a, b) {
    return (a & 1) - (b & 1) || a - b;
});
