Furthermore, from what I see, a lot has changed in JS land. You can basically assume ES2018, with a few exceptions in the library, module systems are part of the standard now, and package managers seem to catch up with that. A lot of what you learnt what is older than 5 years about JS and accompanying APIs, you can basically forget now. Arguably, it might even be better if you had never learnt it in the first place. Because, let's face it, what was going on then was a hot mess of steaming shit.
