## What it is
Racket is a mature, general-purpose programming language and ecosystem designed for language-oriented programming, with a core implementation plus a large package distribution. It includes DrRacket IDE, the raco command-line tooling, a package manager, Typed Racket, and Scribble documentation tooling.

## Use cases
- create domain-specific languages with macros
- learn programming and programming language theory
- build cross-platform GUI applications
- write web server applications
- gradually type Scheme-like code with Typed Racket
- script and prototype quickly in a Lisp
- generate documentation with Scribble

## When to choose
- you want a mature Lisp/Scheme descendant with batteries-included libraries
- you are designing or teaching programming languages
- you need powerful macros to build embedded DSLs
- you want an integrated IDE, docs, and package system out of the box

## When to avoid
- you need maximum raw runtime performance or low-level systems control
- your team requires a widely used mainstream language ecosystem
- you need extensive third-party libraries for a niche domain
- hiring for Racket expertise is a constraint
