Clojure is a serious contender. To be sure, it's still niche but it has a good ecosystem, piggybacks on mature java libs, and has an active community. It's thoughtfully opinionated, which I appreciate. Also clojurescript is almost the only front end dev experience I will tolerate. The hot reloading is magic and it is gangsta as F to use the exact same logic on the fast jvm (or CLR if you're nasty) backend as in the js front end.
