Clojure has had things like Parenscript for a while, including scriptjure (~1.75 years old) and clojurejs.

Even worse, two other relevant Clojure libs are mentioned and the important point is still "it's Clojure"?
ClojureScript is a Clojure The Language compiler that implements Clojure (its datastructures, standard lib, protocols, deftypes etc etc) and is hosted[2] on javascript rather than the JVM.
In ClojureScript you are not writing reskinned javascript, you are writing Clojure.
