Where it wins
- Compiles Clojure to JavaScript with Google Closure-compatible output and optimization.
- Supports browser, Node.js, Web Worker, and bundle targets.
- Includes browser and Node.js REPLs, npm dependencies, macros, and source maps.
Where it doesn't
- The toolchain is centered on Clojure rather than multiple source languages.
- Its feature set may be more than needed for projects that only require JavaScript.
- Support channels are documentation and community.

Our verdict on ClojureScript

ClojureScript is an open-source compiler and programming language for building JavaScript applications from Clojure code. It is aimed at developers and teams who want to use Clojure’s functional language features for browser or JavaScript-based projects, including applications targeting Node.js. It converts source code to JavaScript and offers command-line compiler access through cljs.main, along with API access. Its language focus makes it a fit for Clojure teams, rather than developers seeking a general-purpose transpiler across source languages.

Its target options cover browser, Node.js, Web Worker, and bundled output. Browser and Node.js REPLs support interactive evaluation, while JavaScript and npm dependency support helps connect projects to JavaScript packages. Google Closure-compatible output and optimization modes address compilation and output handling; source-map generation can aid debugging. Macros and multiple compilation stages provide additional control over how Clojure code is compiled. Optional self-hosted evaluation and analysis-cache loading extend the toolchain for teams that want those capabilities.

ClojureScript is open source and self-hosted, with documentation and community support channels. Its command-line access and API fit developer workflows, while support for Windows, macOS, and Linux broadens where the toolchain can run. The central tradeoff is language specificity: teams already working in Clojure and targeting JavaScript can draw on its compiler, REPLs, and ecosystem support, while teams whose codebase or source language is not Clojure should look for a transpiler aligned with that stack. Choose it for Clojure-to-JavaScript work; skip it when that conversion is not the goal.

How long have you used it?

I've used ClojureScript myself and this is my honest opinion — nobody paid or asked me to write it.
