JavaScript because you want to focus on web. As a UX designer I imagine you'll want to work on front end at least to some extent even if you learn backend too.

JavaScript because you want to focus on web. As a UX designer I imagine you'll want to work on front end at least to some extent even if you learn backend too. The other languages are fine but they're only for backend work and at some point you'll have to learn JS for the front end anyway. So you might as well start with JavaScript which can do both. It really seems like a no-brainer for your requirements; don't worry too much about other people complaining about stuff - you can find complaints about every programming language out there.
