A quick update on the JS Ecosystem​

• A new StarlingMonkey release
  • Great job by Tomasz on updating to the latest version of StarlingMonkey
  • https://github.com/bytecodealliance/StarlingMonkey/releases
• componentize-js is being rewritten
  • Joel has ported componentize-js to Rust and implemented guest p3 (async, streams, etc)
    • https://github.com/dicej/componentize-js
  • This uses wit-dylib, a crate that can be used to implement components for interpreted languages (think Python, Ruby, etc)
    • https://github.com/bytecodealliance/wasm-tools/tree/main/crates/wit-dylib
• componentize-qjs
  • Tomasz has been working on getting quickjs-ng working with wit-dylib
  • https://github.com/andreiltd/componentize-qjs
  • At some point, componentize-js should become a multi-guest-runtime project
• Jco p3 host suport
  • Jco p3 host support now has streams merged, with work right now testing out lowering/lifting for all the types
  • Only futures left
  • Check out the tests for streams: https://github.com/bytecodealliance/jco/blob/main/packages/jco/test/p3/stream.js
  • New version of Jco is out so you can try things today (and file bugs if something is broken!)
    • https://www.npmjs.com/package/@bytecodealliance/jco/v/1.17.2
• Someone vibecoded a fully JS host implementation
  • Jelles has done amazing work including a sweet demo of Go running in the browser
  • https://github.com/jellevandenhooff/wcjs
  • We want to get this merged upstream in the Jco project someday, so we can be a multi-host-runtime project
  • AIs can now output WebAssembly host implementations, including custom parsers and visitors for operations (!!)
