## What it is
Planck is a stand-alone ClojureScript REPL for macOS and Linux built on JavaScriptCore. It launches instantly and supports writing Clojure-idiomatic scripts with file I/O and shell integration.

## Use cases
- run a ClojureScript REPL without a JVM or browser
- write Clojure-idiomatic shell scripts
- quickly experiment with ClojureScript from the terminal
- evaluate ClojureScript expressions interactively
- script file processing using planck.io and planck.core

## When to avoid
- you need a browser-based ClojureScript development workflow
- you require JVM Clojure rather than ClojureScript
- you need Windows support

## Facets
- artifact type: cli-tool
- maturity: maintenance
- function: interpreter, cli, developer-tools
- domain: programming-languages, developer-tools
- platform: cli
- tags: clojurescript, repl, javascriptcore, scripting, lisp, command-line, automation, macos, linux
