boa VS quickjs

boa

Yeah, pretty much. I'm not sure if we're gonna need to implement Static Shapes first but at least we need to make it possible to separate codeblocks from contexts for this to be feasible.

Hi, I'm looking for full time work and I'm interested in roles related to compilers, developer tools and systems. I'm a college senior(graduating on May, 2023) and have been working as an [IOS Developer](https://www.cyengagement.org/) for the past two years. At University, I took a compilers class where I learnt to use LLVM and MLIR to compile programs to various architectures. In Oct. 2022, I was selected to attend the [Programming Language Implementation Summer School](https://pliss.org/2022/) where I got to learn about compiler implementation and language tools from leading researchers around the world. Recently, I have been contributing to [Boa](https://github.com/boa-dev/boa), an embeddable Javascript engine written in Rust, by fixing issues and implementing features to improve conformance with ECMAScript specification. Aside from working on compilers, I have volunteered at conferences like ICFP'21 and PLDI'22 to familiarize myself with latest research in the field of compilers. You can find more information about me and my work in my [blog](https://veera.app) and Github [profile](https://github.com/veera-sivarajan). Thank you for your time and consideration.

I have great news

I already use it in my project to run some parts of the youtube js player. I must say it was broken on one version of the player because of a generated regex inside (more on the issue), but definitely recommending.

I would be curious how much effort it would be to swap boa for V8 to have an all Rust runtime :) If it's not meant to be a production-ready project anyways.

We'd love to see these benchmarks too! We have an open issue to set-up these benchmarks: https://github.com/boa-dev/boa/issues/1924

Although you probably could use it for something else, Boa[1] is a good demonstration of this (it uses the GC crate, but the same principle probably applies).

It uses service workers to cache static files, by the time it opens up you already free to be offline, try toggle network switch to verify.

It has download link at bottom of the about page ([accdoo.app/about]) which you could then self host it by dropping into any static hosting services.

btw, the Pi feature was by-product from the original App but I won't expand here, if you'd like to learn more, please checkout its two Show HN post (39115559 and 39138957) previously.

Just go with quickjs, I think this is what you are looking for.

QuickJS

I think QuickJS, written in C, is a user-"friendly" starting point for implementing ECMA-262. Documentation QuickJS Javascript Engine.

There is a readme on the project's main page: https://bellard.org/quickjs/

The newsworthy bit here is that the activity seemed to have stalled for year or two and now Fabrice pushed a few fixes and made a new release.

Just to demonstrate GitHub repositories do not necessarily reflect upon a programmers' body of work, Fabrice Bellard has one (1) repository published on GitHub, quickjs. Compare the list of work on Bellard's home page https://bellard.org/.

> I am still confused, it's a JavaScript runtime intended to be deployed to JavaScript/Wasm runtimes?

Seemingly.

> Why does a JavaScript runtime need a JavaScript runtime?

Because if you want to create a Service Worker server for CloudFlare Workers and other JavaScript/Wasm runtimes, that's the only option for doing that AFAIK.

FWIW, this isn't a new idea. For example, Figma uses QuickJS (https://bellard.org/quickjs/) for their plug-in runtime: https://www.figma.com/blog/an-update-on-plugin-security/
