JavaScript JavaScript Foundations Arrays Methods: Part 2

Methods part 2 - Sort the 'saying2' array, on about line 19, so that the words are listed in length order. The shortest

Getting this error am i misunderstanding the question?? 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'.

My Code:

    a.length + b.length ;

this is the full 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"];
  saying2.sort(function(a , b){
  return (a - b .length);

You're close in the code you posted as an answer.

Should be return a.length - b.length;
