Aside from "this", all failure modes in Javascript are pretty obvious to google and figure out (unlike a segfault in C++), so I'd suggest just diving in and implementing something in it, if you already have programming experience. However, just being able to do something in a language and being able to do it the most correct and future-proof way is different, and in JS, "best practices" seem to be constantly evolving with language and community. Every library and framework seem to be doing things in a slightly different way, and there's a lot of freedom to experiment with different coding styles and programming paradigms (unlike in a language like Go). Personally, I would suggest Typescript for professional projects, but there are plenty of very knowledgegble and competent people with a lot of different opinions on it. If you're the kind of person who likes this kind of environment, you'll fall in love with JS ecosystem.
