The main problem that i had with Clojurescript was that it seemed to be quite intensive even for the simple puzzle game that I made. Note that it may be because I hacked the program in one night and probably raped the language horrible. Which is why I'm still open for Clojurescript suggestions by people who have good experiences using it.

I've been using it in production for a number of applications for about 6 months now and haven't seen any performance issues. Prismatic http://getprismatic.com/ and CircleCI https://circleci.com/ both use ClojureScript for their front-ends. CircleCI open sourced their front-end here https://github.com/circleci/frontend/tree/master/src-cljs/fr... as you can see it's a decent size app, and Prismatic have blogged about Om and performance here http://blog.getprismatic.com/om-sweet-om-high-functional-fro...

In general, there should be very little overhead compared to regular JavaScript once the advanced compilation option is used.
