## What it is
CodeWorld is a web-based educational programming environment built on Haskell, letting students create geometric drawings, animations, and games with zero setup. It compiles code in the browser via GHCJS and includes an educational Haskell variant plus a drag-and-drop blocks interface for younger learners.

## Use cases
- teach kids to code in a K-12 classroom
- learn functional programming with Haskell in the browser
- build simple animations and games as a student
- run a zero-install coding playground for a class
- teach math through programming with geometric figures
- try Haskell online without installing a compiler

## When to choose
- you teach programming or math to K-12 students and want a zero-setup environment
- you want students to write animations and games using a simple mathematical model
- you want to introduce functional programming in the browser

## When to avoid
- you need a general-purpose production Haskell development environment
- you want native mobile or desktop app development tools
- you need the drag-and-drop blocks interface for critical use, since it is still buggy

## Facets
- artifact type: application
- maturity: stable
- function: compiler, editor, interpreter
- domain: education, programming-languages, web-development
- platform: browser
- tags: haskell, ghcjs, k12, functional-programming, learn-to-code, playground, block-programming, education, game-development, web-server
