My first "serious" programming language was JavaScript, and I didn't know a lot of basic stuff for a long time – because it is considered normal in JS community! Nowadays we have node.js, so you have to know at least a bit about your terminal, how to run server, kill processes and other everyday stuff, but back in the days it was unnecessary. And this is not a single story; I've also interviewed some people and for some reason my experience is that JS has very low entry barrier. Yes, with tail recursion we'll have almost full FP (only pattern matching is missing), but it doesn't mean that every novice will go and study them right after landing – in fact, the opposite, because there are much more tutorials about OOP JS.
