Sort function

what do you mean by this? can you provide more in depth description of what your trying to do?

When I do the exercise 2 of method parts 2 of js, I must utilise the function sort and in this function I should the length property to sort an array.

Hi Piero!!! In exercise 2, it's asked you to sort the word length in order.

So you have to use method array.sort(sortfunction) and write your own function to solve the right problem

The code should be like this:

saying2.sort(function([parameters]){
        //your code
});

Like Sreng Hong pointed out, you'll need to write your own code, but it involves comparing the lengths of any given string within the array. It takes a little more brainpower than the web design exercises, but you can do it.
