There certainly are universities out there with proper CS courses teaching way more than Java and JS so your point is a bit moot. But that doesn't take away that I also have the impression that universities alone do not produce people capable of programming proficiently in anything at all especially not when it comes to programming complete programs of anything more than very small scale. They simply can't because that takes experience in writing actual software. Whether people get that before they even were in uni of after doesn't really matter it seems. All anecdotal, but I've seen a bit too much people with CS degrees who were clever enough, had all the knowledge, could produce smart algorithms and everything you want. But the code would just work and that's that. Like: build process only works on their machine, git history like written by a child or non-existent, code impossible to integrate in other projects, trainwreck-like, violating anything you can think of and so on. Is that bad? Well, yeah, but it's also pretty normal and it's not always problematic: teach them some more in an actual team and the really good ones will be better than you in no time.
