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.

Can the PineTime Watch stream music without a phone? (Onboard music storage)
There are subsets of JS for embedded device e.g. Espruino https://github.com/espruino/Espruino for BangleJS https://shop.espruino.com/banglejs also with 4MB or JerryScript https://jerryscript.net

[AskJS] Do you use JavaScript on Microcontrollers? Which engine / interpreter?

An ES5-compliant JavaScript interpreter, written in Java
I would guess that depends on the licensing context in which it will be running, since Rhino is MPLv2 <https://github.com/mozilla/rhino/blob/Rhino1_7_14_Release/LI...> and OP's repo is MIT whereas Graal is UPLv1 <https://github.com/oracle/graaljs/blob/graal-23.1.2/LICENSE>. GitHub's license gizmo claims it is OSI/FSF approved, but Oracle gonna Oracle and they for sure have more lawyers than you do

No one cares about Bun's speed. Your CI does though
It's by Oracle: https://github.com/oracle/graaljs; seems to be built to interop w/ GraalVM based languages/services

R Shiny App Equivalent
If you need you can run JavaScript from within Java using Graal.js or Nashorn. To evaluate dynamic user input (Strings) you could also use a ScriptEngine (e.g. JavaScript) or dynamically compile inputs to Java using the JShell API.

CoWasm: An alternative to Emscripten, based on Zig (demo: Python in the browser)
That's just incredibly cool, my congratulations!
Foremost, my apologies if this is a nonsensical question. I haven't been soaking in the WASM ecosystem enough to know how much WASM is "just" JS versus ... something else.
Caveat aside, I saw one of the commits mention jython, which notoriously has ancient (and probably incredibly incomplete) python 2.x support; do you know if python-wasm would run on top of GraalJS (https://github.com/oracle/graaljs#nodejs-support)?
Separately, do you want issues related to zython.org in the cowasm issue tracker? It returns 405 (method not allowed) over and over on POST https://zython.org/python-wasm-sw/read-signal for me

Dear Oracle, Please Release the JavaScript Trademark
