How To Sort Numbers

You cannot simply add an array of numbers and expect sort() to take care of it. For example, it will see 10 as smaller than 9.

If you wish to sort an array of numbers, you need to create a function such as seen below.

JavaScript Code

var points = [40, 100, 1, 5, 25, 10];
points.sort(function(a, b){return a - b});
