## What it is
Apache Groovy is a multi-faceted programming language for the JVM that offers Java-like syntax with productivity features such as closures, builders, traits, and both dynamic and static typing. It interoperates bidirectionally with Java and supports scripting, DSL creation, and compile-time/runtime metaprogramming.

## Use cases
- write concise scripts and automation glue on the JVM
- build domain-specific languages for business rules
- write maintainable tests for Java applications
- gradually migrate or augment Java codebases with a more expressive language
- process JSON, XML, YAML, and SQL data with concise syntax
- build web and reactive applications using the Groovy ecosystem

## When to choose
- you want Java interoperability with a more concise, flexible syntax
- you need scripting or DSL capabilities on the JVM
- your team knows Java and wants a flat learning curve
- you need both dynamic and static typing options in one language

## When to avoid
- you need maximum raw performance with no dynamic language overhead
- your team has no JVM experience and prefers non-JVM ecosystems
- you need a language with a very large modern ecosystem outside the JVM
- strict compile-time guarantees are required without opting into static compilation

## Facets
- artifact type: library
- maturity: stable
- function: programming-language, compiler, interpreter, cli, templating, json, yaml, csv
- domain: programming-languages, developer-tools, testing, web-development
- platform: jvm, cross-platform, cli
- tags: jvm-language, dynamic-typing, static-typing, metaprogramming, dsl, scripting, closures, gradle, apache-software-foundation, xml, jvm, automation
