it asks to sort by length starting with shortest.
this is what I have: (saying 2)
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 () {
return Math.length;
please help this is so frustrating.

Here is some reference regarding the behavior of sort: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/sort
So, firstly there is no property length on Math. What you need to do is pass two values into the comparison function to compare. You would compare the lengths of them in this case. If the first designated parameter's length is shorter than the second's, you return a -1 or else you return 1
var compare = function (x, y) {
if (x.length < y.length) { return -1; }
return 1;
}
