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.

Is there a safe and robust interpreter/scripting language? Or should I write it myself?
Your project might be a good candidate for the Moddable SDK: https://github.com/Moddable-OpenSource/moddable In particular the "mods" feature that allows sandboxed user scripts.

The Story of Mel, a Real Programmer
> meaning that to deploy those apps requires embedding an entire web browser into every app
It doesn't require it, that's just what they choose, and it has little to do with the language. (Besides, if you actually observe them—and ignore what they tell you about liking JS—then it's clear that most of them hate their preferred language.) Languages and the bindings that a particular runtime exposes are orthogonal. You can have GTK apps written in JS, for example, or you can write a program in JS that compiles into a binary that runs on a microcontroller[2].
This is much more of a problem with the culture of Electron and the adjacent NPM ecosystem than it is anything else. Conflating the source of these problems is a great way to tank any would-be activism meant to solve them.

Microvium Is Small
I experimented with Moddable some time ago and also contributed a module for Linux. It's written in C and I found the code quite readable, and the entire architecture good too. It's almost ES6 complete too.

Pikascript: An ultra-lightweight Python engine that can run in 4Kb of RAM
There's JavaScript/ECMAScript via Moddable's XS engine: https://github.com/Moddable-OpenSource/moddable
"A typical microcontroller used with the Moddable SDK has about 45 KB of free memory, 1 MB of Flash ROM, and runs at 80 MHz. The Moddable SDK uses many different techniques, both at build time and at run time, to work efficiently on these devices."

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/.

WinterJS
> 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/
