1,447 PointsIn JavaScript Foundations, I'm stuck on Arrays/Methods-2, Challenge Question 2. Is there somewhere I can get the answer?
How do you sort 'the values of an array', from shortest to longest, based on the 'length of each individual value'?
The values are all strings, and apparently, I'm supposed to use the 'length property' in the 'sort' function.
This is the actual array in the challenge question:
var saying2 = ["The", "quick", "brown", "fox", "jumped", "over", "the", "lazy", "dog's", "back"];
Stuck!

return a.length-b.length;

1,447 PointsIt's simple now seeing your answer, but I could not come up with that conversion on my own. Thanks Julian.

saying2.sort(function(a, b) { return a.length > b.length; });
- which, in my console works no problem, but the code challenge wouldn't accept it. Is there a reason the "-" is better to use than the > ?

8,215 PointsJust a beginner as well but my hunch is that a.length > b.length returns a boolean value whereas using - returns an int value? Now why the latter is better than the former I have no idea.
