Having problems with question 2. Tried various solutions like below 

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

This worked for me:

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

Cheers!

You're pretty close.

When dealing with arrays we use square brackets '[]`, whereas functions use rounded brackets '()'.

When you write saying2(a) this is like calling a function named saying and passing an argument of 'a'. That being said, you don't need to do this at all since the values a and b are items within the array that are looped through.

Also, for this function to perform you need to return something.

The body of the function should look like:

return a.length - b.length;
