## What it is
Slang is a small audio programming language implemented entirely in JavaScript, running in the browser on top of the Web Audio API. It uses Ohm.js for parsing and CodeMirror for its in-browser editor, letting users define synthesizers and drum machines with sound lines and sequence them with play lines.

## Use cases
- livecode music in the browser
- learn how to build a programming language from scratch
- create synthesizers and drum machines with a simple DSL
- experiment with the Web Audio API through a text language
- teach audio programming concepts interactively

## When to choose
- you want a lightweight, browser-based livecoding environment for making music
- you want a readable example of implementing a language with Ohm.js and Web Audio
- you want to teach or learn language design and audio synthesis together

## When to avoid
- you need a production-grade audio language with robust error handling and tooling
- you need offline or native audio synthesis
- you need an actively developed or comprehensive language - the project is a personal exploration with sparse maintenance

## Facets
- artifact type: cli-tool
- maturity: maintenance
