like with the built-ins themselves, you don't need to memorize the rules and symbols
in fact, that's probably counterproductive - it's more important to understand the core concepts and then just refer to docs for everything
it's like how as a chemist understanding the procedure is important and memorizing the table isn't, which is why the education system always tests you on the important understanding and not pointless memory related things, right? oh wait
hm. idea. video series to teach jelly? :p
probably not enough audience to be worth the effort tho ¯\_(ツ)_/¯
