Ask HN: Advantages of ClojureScript and OM vs. ES6/7 and React?

I have limited time for a side project, I decided I'll do it in React. Not sure if should be learning the new ES6/7 features or spend that time learning ClojureScript, I don't have previous knowledge of Clojure nor Lisp. I'm concern about advantages / disadvantages, and the learning curve. Thanks.
