How will the javascript version of the closure compiler effect planck long term? 🙂

Well, it certainly opens the door for actually building a full-fledged compiler using self-hosted ClojureScript.

(But, in some sense, Closure is about targeting environments where you need to minify—as far as we know, the speed optimizations wouldn’t likely help something like Planck.)

but being able to do production quality cljs-dev without a jvm might bring clojurescript to a much wider audience 🙂

I’m not sure why dead code elimination wouldn’t help planck projects, though? I guess because downloading the bundle isn’t a problem?

Right. Presumably Planck doesn't need to deal with optimizing for download.
