How can I apply the length property on the strings in the sort function?

I'm stuck on a code challenge, I'm trying to sort an array based on the length of each item. I know I can access the length of an item within an array by using array[1].length but I can't figure out how to use that within the sort function.

An array's sort() method accepts one argument which is a comparison function.
The following code should do it:

array.sort(function(a, b){
    return a.length-b.length;
});

Thank you! I messed with that forever and was over complicating it. That was way easier that I was making it : )
