I'm sure this question has been asked numerous times before, but the search feature will not behave.
Anyways, what runs the advanced editor? I would assume it's HTML--I believe that's what runs this website--but then how would you be able to make computations? Is HTML capable of that?
Or rather, is it Javascript? Really, I am not getting much out of the few snippets of code I managed to find in the forum. At any rate, I need to know what I'm trying to learn before I can begin learning it!
