javascript String() method issues or sort() method?

Question

I'm running into some issues with the javscript String() method.Consider the following example.

var myArray = [10,1,5,15];
myArray.sort();
console.log(myArray) //Logs 0,1,10,15,5 to the console

Is this an issue with the sort() method? Or is the string value of 10 and 15 actually less than the string value of 5?

Answer 1

Yes sort is only sorting alphabetically. Below is alternative way of sorting

function sortNum(firstelement,secoundelement) {
    return firstelement - secoundelement;
}

var numArray = [10,1,5,15];
numArray.sort(sortNum);
