I wasn't aware that JS was used in CS university courses, but I'm not so offended by it. The nasty parts of JS (type coercion WTFs, void, with, etc.) aren't very relevant to teaching basic CS principles, and it's got everything you need unless you consider "normal" object-orientation a basic CS principle. It's got all the flow control, loop constructs, obvious anonymous function syntax, etc. you would expect.
Additionally, it's one of the only popular prototype-oriented languages. I think having to teach some of the less-than-sane parts of javascript can be a distraction from whats important in a 100 level course, but for a higher level course that teaches different paradigms, it makes sense to teach Javascript.
