I don't know how to sort the array by the length of the strings. Thanks

here is an example from the mozilla docs:

var numbers = [4, 2, 5, 1, 3];
numbers.sort(function(a, b) {
    return a - b;

which sorts an array of numbers. we want to sort by the length of strings, so we will need to use .length on a and b

so it should look something like this:

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

a.length - b.length sorts it in ascending order b.length - a.length sorts it in descending order

Thanks mate!
