Patterns in javascript?

I recently started my first project in node.js, and I'm struggling with my code. I was always used to languages like Java or frameworks like Angular, where more or less the code respects the classical oop paradigm, but with node I realize that it's not always the good way, even with typescript. I tried to think in oop but I'm not confortable, at least in my specific case.

All this asyncronous stuff, both with callback functions and/or promises sometimes make me feel like my code becomes quickly spaghetti. So I am asking you guys if you could please link some good tutorial or some codebase with nice examples of how to use asynchronous stuff in a clean way.

I'll keep looking on github for the source code of some famous library/framework and try to study them, but some tutorial would be nice...

Thanks in advance.
