Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Nice!
> It's also possible that the way I'm compiling things down to Racket is defeating optimizations, but I haven't yet dug in.
Part of the secret of the reimplementation Racket on top of Chez Scheme is that there are many macros pretending to be functions. The optimization pass inlines some of the functions, but sometimes the heuristic is not good enough, and you must cheat using a macro. (And sometimes the "obvious" improvements are wrong, and using a macro to force the expansion of the code has a worse result.)
For example in https://github.com/Bogdanp/racket-lua/blob/master/lua-lib/pr... I'd try using a macro to inline the fast case where both numbers are exact integers, and then call a real function for the slow cases. (Is it common that someone wants to use 7.0 to do bit operations? Perhaps it's better to inline more. That's the tricky part, understanding which is the best split. I'm not sure. Probably only Matthew knows.)

Show HN: Happy Pi day with this PWA to cut 100k Pi digits offline
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.

Can you make your own JavaScript by implementing ECMAScript standard?
I think QuickJS, written in C, is a user-"friendly" starting point for implementing ECMA-262. Documentation QuickJS Javascript Engine.

New QuickJS Release
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.

GitHub
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/
