Usually a React dev, have been some other stuff, but generally yeah, websites. Anything from resort chain websites to complex internal applications. Unit tests were optional at best in most jobs I've been at. I've heard of jobs where they're pulled off, but from what I've seen, those are the exception and not the rule.
Edit: given the downvotes on my other comment, I should add that this is both anecdotal and unopinionated from my behalf. My opinion on unit testing is "meh", if I'm asked to do tests, I'll do tests, if not, I won't. I wouldn't go out of my way to implement them, say, on a personal project or most work projects, but if I was tasked to lead certain project and that project could clearly benefit from them (i.e. Fintech, data security, high availability operation-critical tools), I wouldn't think twice about it. Most of what I've worked on, however, has not been that operation-critical. What few things were critical in my work experience, would sometimes be the only code being unit tested.
Can't relate, just upgraded my laptop from 32GB to 64GB since VScode would keep closing due to OOM. What? Oh, no, it's not vscode's fault.....I keep like 5 Firefox windows with 30+ tabs open, like a fucking maniac..... Close them? What do you mean "close" them?
