So the question is asking you to sort the Array by the shortest number of characters, to the greatest number of characters.

To do this you will need to add a compare function which the sort() function calls.

it will look something like this:

<!DOCTYPE html>

<script>
var saying2;

saying2.sort(function (a, b) {

        var compare = a.length - b.length;

        return compare;
</script>

What i did here was passed an anonymous function to the sort argument which then converts arguments a and b to numbers. Once compared it places the value back into the array. i suggest you look at the MDN site for a more better understanding of how it works.

I hope this helps.

If you have any more questions feel free to ask.
