In their own words
ClojureScript
ClojureScript is a compiler that turns Clojure code into JavaScript for client and embedded application development wherever JavaScript reaches. It brings Clojure data structures and constructs—including functional programming, macros, destructuring, and polymorphism—into JavaScript environments. Its output is compatible with Google Closure Compiler advanced compilation, which can minify output and eliminate dead code. REPL support enables interactive development and testing in a browser or Node.js; the quick start uses browser output by default and selects Node.js output with a target setting. ClojureScript supports both ClojureScript and JavaScript dependencies, with React demonstrated in the quick start. Listed build tools include shadow-cljs, Figwheel, Leiningen, and lein-cljsbuild. Editor resources cover Cursive, Emacs, VS Code, Light Table, Sublime Text, Vim, and Atom. Documentation includes compiler and REPL options, dependencies, advanced compilation, source maps, and JavaScript module support marked Alpha. The project is open source under the Eclipse Public License 1.0 and lists Linux, macOS, Windows, web, and self-hosted environments.
