ToyJS is a minimal JavaScript runtime built with Rust and V8. It serves as an educational project to understand how JavaScript runtimes (like Node.js or Deno) work under the hood, featuring a custom event loop, native bindings, and ES module support.

• V8 Engine: Powered by the V8 JavaScript engine.
• ES Modules: Support for import and export syntax.
• Native Bindings:
  • print(msg): Print to stdout.
  • add(a, b): Simple synchronous addition.
• Async Support:
  • setTimeout / setInterval: Timer operations.
  • fetch: Basic HTTP requests (returns a Promise).
• Event Loop: Custom implementation using tokio to handle asynchronous tasks.
