Yesterday, a friend asked me to explain LL(1) to him, so he could beat his boss today.

I suddenly wondered, if there are a lot of YouTubers making tutorials about programming languages, frameworks, etc., explaining them in a very leisurely way. Then why there are literally nobody making videos about compiler/parser technics in a similar way? I searched youtube, and all results are very serious and make me feel like I'm in college.

(Context: When I was learning compiler in college, my teacher gave us a MOOC URL and told us to watch that again and again until we figured out any questions we had. She literally does not accept any questions in class.)
