Hello @digital4606319117, welcome to the forums! If you’re confident with your ability to learn new things, then you don’t really need anything. However, if you wanted an introduction to coding concepts, CC offers a course called something like
Learn to code-which introduces the concepts of code.
Java in their names.
HTML would be good. Maybe CSS also is productive. In my personal experience I only learned HTML before (I still don’t know CSS well-enough) and JS has gone good for me.
PS: I’ve also done the A-frame course and I have to admit I have problems with libraries tho. Frameworks are more difficult. But one step at a time.
