## What it is
The Scala 2 programming language compiler and standard library, hosted by the Scala organization. Scala 2 is in maintenance mode, with active development focused on Scala 3 in the scala/scala3 repository.

## Use cases
- compile scala 2 code
- functional programming on the jvm
- build scala standard library from source
- contribute to scala 2 compiler
- maintain legacy scala 2 projects
- learn scala programming language

## When to choose
- you maintain or build Scala 2 codebases that cannot yet migrate
- you need to fix or extend the Scala 2 compiler or standard library
- you target the JVM with a hybrid functional/object-oriented language

## When to avoid
- you are starting a new project - use Scala 3 (scala/scala3) instead
- you need a non-JVM native language
- you want a language with active new feature development

## Facets
- artifact type: library
- maturity: maintenance
- function: compiler, interpreter, programming-language, parser
- domain: programming-languages, compilers, developer-tools
- platform: jvm, cross-platform, cli
- tags: scala-2, standard-library, functional-programming, object-oriented, jvm-languages, compiler
