Vanilla JS is best I recommend sticking with that and improving your skills. Everyone thinks they need a framework but Vanilla is powerful if you know what you are doing
Technically you are correct, I never use frameworks for other things. I program mostly in Python, PHP, C and C# - but I am in the mood for using one and I need to rapidly develop this... and quite frankly I don't like to do frontend so it's much more fun this way. The goal is to write as little code as humanly possible.
