## What it is
A rewrite of the CoffeeScript compiler built with proper compiler design principles, emphasizing robustness and extensibility. It compiles CoffeeScript source code to JavaScript via a clean lexer/parser/AST pipeline.

## Use cases
- compile coffeescript to javascript
- rewrite of the coffeescript compiler with better architecture
- parse coffeescript into an AST
- extensible coffeescript compiler for tooling
- replace the original coffeescript compiler

## When to choose
- You need a more robust, extensible CoffeeScript compiler than the original
- You want programmatic access to a CoffeeScript AST for building tools
- You're compiling CoffeeScript in a Node.js project

## When to avoid
- You're starting a new project (CoffeeScript itself is largely legacy; prefer modern JavaScript or TypeScript)
- You need the exact behavior of the original jashkenas compiler without deviations
- You need actively maintained tooling with recent updates

## Facets
- artifact type: library
- maturity: maintenance
- function: compiler, parser, developer-tools
- domain: compilers, programming-languages, developer-tools, web-development
- platform: cli, cross-platform
- tags: coffeescript, transpiler, javascript, compiler-rewrite, nodejs
