## What it is
Pyret is an educational programming language that blends scripting, functional, and object-oriented styles, designed primarily for teaching programming. This monorepo holds its implementation: the compiler and standard libraries, the code.pyret.org web-based IDE, an npm CLI/embed package, a CodeMirror mode, and a VS Code extension.

## Use cases
- teach beginners programming with a gentle scripting language
- run Pyret programs from the command line
- embed an interactive programming playground in a webpage
- learn functional programming in the browser without setup
- find the language used by the Bootstrap curriculum
- build editor support or tooling for the Pyret language

## When to choose
- you are teaching introductory programming and want a language designed for pedagogy
- you need a zero-install, browser-based IDE so students can start coding immediately
- you want a small language mixing functional and object-oriented concepts with gradual typing

## When to avoid
- building production software that needs a large ecosystem, long-term guarantees, and industry tooling
- high-performance, systems, or concurrency-heavy workloads
- you need a mainstream language with extensive third-party libraries and hiring pool
