## What it is
Clojure is a dynamic, general-purpose Lisp dialect for the JVM that compiles to Java bytecode while remaining fully dynamic at runtime. It emphasizes functional programming with immutable persistent data structures and built-in concurrency support via software transactional memory and agents.

## Use cases
- write concurrent programs without locks
- build JVM applications with a dynamic Lisp
- functional programming with persistent data structures
- interoperate with Java libraries
- rapid REPL-driven development
- build scalable backend services on the JVM

## When to choose
- you want a Lisp on the JVM with access to Java frameworks
- you need robust multithreaded designs with immutable data and STM
- you value interactive REPL-driven development with compiled performance

## When to avoid
- you need a language with no JVM dependency (consider ClojureScript or ClojureCLR instead)
- your team requires static typing or mainstream object-oriented idioms
- you need a large pool of readily available developers

## Facets
- artifact type: library
- maturity: stable
- function: programming-language, compiler, interpreter, concurrency
- domain: programming-languages, developer-tools
- platform: jvm, cross-platform
- tags: lisp, functional-programming, jvm-language, dynamic-language, immutable-data-structures, software-transactional-memory, macros, homoiconic, clojureclr, clojurescript
