How does Javascript return work?

Question

This is what I have

$wrapper.find('li').sort(function (a, b) {
  return +a.getAttribute('data-val') - +b.getAttribute('data-val');
});

It works, as I see in Chrome dev tool an array of objects is indeed returned but...my question is: What's up with that return? How can I use that array?

What I want to do i to take the returned array, and stick it inside a tag.

You should be aware that .sort() isn't a supported jQuery method. — user2736012

Simply assign it:

yourArray = $wrapper.find('li').sort(function (a, b) {
  return +a.getAttribute('data-val') - +b.getAttribute('data-val');
});

You can then use yourArray.

I can't believe I didn't get it! I'm sure I tried something similar but clearly made some mistakes! Thanks a lot!
