## What it is
Joker is a small Clojure dialect interpreter written in Go that also serves as a Clojure/ClojureScript linter and formatter. It offers fast startup, a REPL, script execution, and editor integrations for on-the-fly code checking.

## Use cases
- lint clojure code for syntax errors and arity mismatches
- run clojure scripts with fast startup
- format clojure source files
- try out clojure expressions in a lightweight repl
- check clojurescript code in editors
- write small scripting utilities in clojure

## When to choose
- you need a fast-starting clojure interpreter for scripting
- you want lightweight clojure linting without a full JVM
- you need a clojure formatter in CI or editors

## When to avoid
- you need full Clojure/JVM compatibility and libraries
- you need high-performance compiled clojure
- you need a complete clojure development environment

## Facets
- artifact type: cli-tool
