Where do you see any jQuery? I don't see any $ or jQuery, and if you look at the top left under "Frameworks & Extensions" it is set to "No-Library (pure JS)"

Perhaps the use of the more modern querySelectorAll threw you?

"$" replaced with "elm" to cause less confusion.

I apologise for my confusion and retract my moan.

I'm afraid I suffered from commenting without reading properly. In my defence, seeing $ signs everywhere shuts down the careful part of my brain.

jQuery is not used, $ is just used as a variable name.

There's no jquery here.
