Cant find error in my code challenge

Bummer! The 'saying2' was 'The,quick,brown,fox,jumped,over,the,lazy,dog's,back' not 'The,fox,the,over,lazy,back,quick,brown,dog's,jumped'.

That is the response i get when i run my program.My instructions are to sort the first line in length order, but isnt the answer i gave in length order? My words start off with least amount of characters, and increase to the most amount of characters.

sure this is the question:

Sort the 'saying2' array, on about line 19, so that the words are listed in length order. The shortest first. Use the 'length' property on the strings in the sort function.

and my code:

      var saying1 = ["The", "quick", "brown", "fox", "jumps", "over", "the", "lazy", "dog"];
      var saying2 = ["The", "quick", "brown", "fox", "jumped", "over", "the", "lazy", "dog's", "back"];
      saying1.reverse();
      saying2.sort(function(a,b){
        a.length-b.length;
      })

Hi Cesar

I think your code is correct you just forgot to return it.

It should be:

return a.length - b.length;
