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.

Why doesn’t V8 fit on my microcontroller?
If the scope is limited to ESP32/ESP8266, it seems technically possible to run QuickJS on them.
From Fabrice Bellard himself:
> QuickJS should be able to run on the ESP32 platform as it is OS independent (as you said, quickjs-libc.c is not part of the engine). For simple scripts it should fit in the available RAM.

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.

> 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."
