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.

Elk: A low footprint JavaScript engine for embedded systems
This implementation is nuts. A decent chunk (but still very small subset) of ES5 in under 1400 lines of very readable C code. It includes a mark-and-sweep GC and an FFI.
It doesn't have an AST or a bytecode VM. It just interprets directly off of source code.
Take a look: https://github.com/cesanta/elk/blob/master/elk.c.
This implementation really sets a new bar for me in terms of compact-but-readable language implementations.
Separately, this isn't even Cesanta's only embedded JavaScript implementation. They also have: https://github.com/cesanta/mjs. This implementation is a bit more complete and is much bigger.

What is your programming stack, as well encryption with ESP32?
In the past I've programmed with ESP8266 with Mongoose OS using mJS - https://github.com/cesanta/mjs but it has on 1.5K GitHub stars and I assume there are other alternative as well for Python language

- STARFIELD:Sooooooo the Founder's watch is just Bangle 1 Open Source?
- Firmware changelog?
-
Gadgetbridge is an Android application for your smart watch and other devices
The Bangle.js 2 is an excellent device. As a former Pebble user, this is the first device that I consider an adequate replacement for my Pebble (which by now has a diminished battery life and corroded charging contacts).
Here is my impression of the Bangle.js 2:
- Battery: Lasts about 3 weeks on a charge, constantly connected to my phone, when the watch is used to display notifications and alarms. This is a major advantage over Apple Watches and Android/Wear OS watches.
- Display and buttons: The 1.3" 8-color transflective display is comparable to the Pebble Time series' 64-color transflective display. The display is always on, and the backlight activation is highly configurable. The Bangle.js 2 has a touchscreen and 1 button, while Pebble watches have no touchscreen and 3 buttons.
- Software: Runs on the completely free and open source Espruino JavaScript interpreter,[1] which was my main motivation for purchasing this device. There are currently 336 apps in the web-based Bangle.js app loader (app store), including utilites and clocks (watch faces), all of which are FOSS. The bootloader and firmware can be updated directly from the app loader. On Android, there is a distribution of Gadgetbridge (built from the same code base as Gadgetbridge) with internet access enabled that integrates the Bangle.js app loader into Gadgetbridge, which makes it very easy to use the watch.[2]
- Build: Built on the same device body as the SMA Q3.[3] The casing is plastic, and the watch is compatible with standard 20 mm watch straps. The IP67 water/dust resistance makes the watch usable for sports.
Overall, I highly recommend the Pebble.js 2 watch, which is the best FOSS-focused watch I have found to date.
