ClojureScript

What it does: ClojureScript is a compiler for Clojure that emits JavaScript.
Optimization: Its JavaScript output is compatible with Google Closure Compiler advanced compilation, which can minify output and eliminate dead code.
Language features: It brings Clojure’s rich data structures, functional programming, macros, reader, destructuring, and polymorphism constructs to JavaScript environments.
Interactive development: The compiler supports REPLs for interactive development and testing in a browser or Node.js.
Runtime targets: The quick start describes browser output by default and Node.js output when the node target is selected.
JavaScript dependencies: ClojureScript supports including ClojureScript and JavaScript dependencies, and its quick start demonstrates using React.
Build ecosystem: The maker’s tools page lists shadow-cljs, Figwheel, Leiningen, and lein-cljsbuild as build tools.
Editor ecosystem: The tools page lists editor support resources for Cursive, Emacs, VS Code, Light Table, Sublime Text, Vim, and Atom.
License: Use and distribution are covered by the Eclipse Public License 1.0.
Development prerequisites: The quick start specifies a browser and Clojure for its main macOS/Linux tutorial, and Java 21 plus the standalone ClojureScript JAR on Windows.
Node.js version: The quick start says that only stable Node.js versions at or above 0.12.X are supported at the time described on that page.
Debugging: The quick start says source mapped stack traces point to ClojureScript source locations instead of JavaScript locations.
Documentation: The maker provides API and reference documentation, including compiler options, REPL options, dependency handling, advanced compilation, source maps, and JavaScript module support marked Alpha.
Intended use: The rationale describes ClojureScript as a way to use Clojure for client and embedded application development wherever JavaScript reaches.
