Hi, I'm another one of the maintainers on the project.

In general, we are shifting more to performance now than conformance. We currently sit at around 94% conformance, so there's not really that much more to go conformance-wise. The remaining conformance gains are a couple of the newer specification features and Intl related features. Our current conformance can be found at https://boajs.dev/conformance.

Regarding performance, we are already making some gains, with hopefully more to come. The best example of this was probably the updates to script-bench-rs with our most recent release (which can be found at this commit https://github.com/khvzak/script-bench-rs/commit/d9635de77d2...). We still obviously have more to improve on, but we have already made some pretty steady progress from where we were.

EDIT: I forgot to answer your question about v8-jitless. Obviously in the future it would be nice to be able to be more competitive with v8-jitless, but at least for me, I'd just like to focus on improving the Boa overall.

Does Boa support `fetch`? And if so, is it built on Reqwest or Wreq [1]?

I immediately have use for this if y'all have async fetch support. I can use JavaScript as an extension language for our app.

I love how supremely easy it looks to embed in normal Rust apps without a complicated build script. That, to me, is a killer feature.

Really awesome work on this!

[1] Wreq is starting to get popular for its ability to bypass Cloudflare and look like a normal browser

So this is a bit loaded. Short answer: it can.

Long answer: first, `fetch` is a runtime feature, and Boa is first and foremost an engine. So `boa_engine` -- the core project crate -- does not support `fetch` out of the box.

That being said, we do have a `boa_runtime` crate. This crate is not currently a full runtime, but it is a collection of runtime features that have been implemented and can be registered onto the context. `fetch` is one of the features that has an implementation completed in `boa_runtime`, and it does use reqwest if I'm remembering correctly. If you're interested to see some example code of registering features, you can look at our CLI code as an example :)

This sounds really well architected and extensible. I've gotta check this out.

Thank you!
