## What it is
A simple meta-circular JavaScript interpreter written in JavaScript, intended as a toy/educational project demonstrating interpreter design. It parses and evaluates JavaScript code using JavaScript itself as the host language.

## Use cases
- understand how a JavaScript interpreter works internally
- study meta-circular evaluation and interpreter design
- run JavaScript code inside JavaScript with a custom evaluator
- learn parser and evaluator implementation techniques
- use as a teaching example for programming language courses

## When to choose
- you want a small, readable codebase to learn interpreter internals
- you need a teaching-level example of meta-circular evaluation in JavaScript
- you want to experiment with modifying language semantics in a toy interpreter

## When to avoid
- you need a production-grade or spec-compliant JavaScript engine
- you require performance, security sandboxing, or full ES standard support
- you need a maintained project with active development or a license

## Facets
- artifact type: library
- maturity: experimental
- function: interpreter, parser, programming-language
- domain: programming-languages, education, developer-tools
- platform: browser, cross-platform
- tags: meta-circular-interpreter, toy-project, educational, javascript-engine, interpreters, javascript, nodejs
