I've been using Clojure on the backend for about 5 years now and find it an absolute joy to work with, having come from a Java background. You get full access to the masses of Java libraries out there as it's on the JVM. Great community support, too. As an addition, there's also ClojureScript for the front-end. It's come a long way recently, and I've been using it for the last couple of years in production (check out reagent and re-frame if you're interested).
