Just to build up your knowledge, I'd suggest practicing to make a game with p5.js. It is really easy to draw thing with and it is very useful for making games, simulations, graph diagrams, etc. That is how you can build some mathematical skills.
You can also learn at freecodecamp in the Javascript section. There are tons of algorithms you can solve.
