ClojureScript
ClojureScript is a compiler for Clojure that targets JavaScript. It emits JavaScript code which is compatible with the advanced compilation mode of the Google Closure optimizing compiler. With ClojureScript, you write browser and web-based applications using Clojure and the REPL, allowing you to write the same Lisp syntax that you are used to in the Clojure ecosystem.
