Sort saying array on line 19, so the words are listed in length order. Shortest first. Use the 'Length' property on the

strings in the sort function.

saying2 = ["The", "quick", "brown", "fox", "jumped", "over", "the", "lazy", "dog's", "back"];

saying2.sort(function (a, b){ return saying2.length })

I'm pretty lost with this question. Not sure how to solve it? Can someone please assist me?

Your function needs to sort the array. Use this

saying2.sort(function(a, b) {
        return a.length - b.length;
      });

You can switch a.length and b.length to return the array longest to shortest as well :)

This one had me stumped for ages too and I realised I was adding parentheses onto the .length property.

Thanks, Bryan H .

Can you explain what a.length - b.length is doing?
