Unless you're going to tell me you're autistic as fuck and have decided to do this anyway why would you hurt yourself trying to develop video games in Javascript? There's a reason people are abandoning that language left and right these days.

I am somebody with a fair bit of experience developing video games so you can ask me about this lol. Also I would not recommend at all necessarily writing something from scratch either, that creates extra headaches and all you're doing is re-inventing the wheel.

Why not use something like Raylib instead?
