How to Sort String numbers using javascript

Question

This is my data ["2","1","10"] . When I am trying to sort these numbers my output is ["1","10","2"] , but my expected output is ["1","2","10] . I am using orderBy to sort these numbers. It sorts depending upon 0 to 9 only.

How can I sort these numbers using js?

Here is my code:

ng-options="option.id as option.roomno for option in frData 
          | unique:'roomno' | orderBy:'roomno' "

Answer 1

function sortNumStr(m,n) {
    return m - n;
}

var numArray = ["2", "1", "10"];
numArray.sort(sortNumStr);
alert(numArray)

Answer 2

You can use the string's native prototype localeCompare function like so:

["2","1","10"].sort((a,b) => a.localeCompare(b, undefined, { numeric: true }))

It works well with numbers among other chars too.
