How to sort numbers in an array in Javascript

Question

var set = [3,100, 70, 55, 47, 202];
var sortedNumbers = set.sort();
console.log(sortedNumbers)

I see the following in the console:

[100, 202, 3, 47, 55, 70]

Why isn't the array sorted?

The sort function treats the array values as strings. Instead you could use:

    function sortNumber(a, b) {
        return a - b;
    }

    var sortedNumbers = set.sort(sortNumber);
