Sort JavaScript String Array containing numbers

I have an array in JavaScript that contains the following:

  • ["Value 1", "Value 5". "Value 10", "Value 11"];

How would I go about sorting this array so that it does not appear as follows:

  • ["Value 1", "Value 10". "Value 11", "Value 5"];

But as:

  • ["Value 1", "Value 5". "Value 10", "Value 11"];

Any help would be great.



If you are enthusiastic about writing it yourself, you can just parse the items with an regular expression and compare the second part. Those will match something like



You need to extract the numeric values from the strings and sort based on those, just like vlood said. For example, try this code:

function mySort(arr)
    var regex = /Value\s([0-9]+)/;

    function map(str) {
        return Number(regex.exec(str)[1]);

    return arr
        function (a,b) {
            var av = map(a), bv = map(b);
            return av < bv ? -1 : av > bv ? 1 : 0;

mySort(["Value 1", "Value 10", "Value 11", "Value 5"]);

you need natural sorting. i don't think there is a built-in implementation in js, but you can use some library. for example: phpjs - natcasesort
