README.md

Boa

This is an experimental Javascript lexer, parser and Just-in-Time compiler written in Rust. Currently, it has support for some of the language.
Build Status

This project is an attempted rewrite of Bebbington's js.rs. Most of the Rust code has been rewritten from scratch.

WASM

This interpreter can be exposed to javascript! You can build the example locally with:

$ yarn install
$ yarn serve

In the console you can use window.evaluate to pass JavaScript in

Roadmap

  • ~string.length~ - works in 0.1.5
  • Adding support for constructors - half working, in progress
  • ~better environment and scope support~ - Finished (05/05/2019)
  • let and const support - Next
  • Better error output
  • Passing test262

Usage

  • Checkout this project
  • Build cargo build
  • cargo run
  • You can make changes to tests/js/test.js and build again
  • If any JS doesn't work its a bug! Please raise an issue
