I haven't used it but here's a 10-part mega tutorial on modern Clojurescript: https://github.com/magomimmo/modern-cljs/

Shameless plug, but I'll do it anyway since it's a direct answer to the question: I'm the (co)author of ClojureScript: Up and Running from O'Reilly.

If anyone wants, email me at the address in my profile and I'll get you a discount code.

http://himera.herokuapp.com/synonym.html from Fogus is also a good starting point to have an overview of how to do things and what is possible. Next stop: modern-cljs as mentioned by pchristensen.
