Javascript Array Sort Custom Comparator June 28, 2011

Javascript Array.sort() allows you to define custom comparators!

var numbers = [10, 20, 5, -10, 30];

// Sorting in ascending order.
numbers.sort(function(a, b){return a-b;});

// Sorting in descending order
numbers.sort(function(a, b){return b-a;});
