DeviceScript: TypeScript for Tiny IoT Devices
I've been having a lot of fun with https://kalumajs.org/ recently for silly JS embedded things. It's been great so far, and has a cool little community!
It's a runtime built on top of JerryScript, which has been pretty neat to look into as well: https://jerryscript.net/

Good example open source C++ embedded projects
Jerryscript came to mind : https://github.com/jerryscript-project/jerryscript
- Arduino Announces MicroPython Support

JavaScript embedded inside Elixir
I personally quite like JerryScript
-
Kaluma - tiny JavaScript runtime for microcontrollers - includes a browser-based IDE that can communicate with a Raspberry Pi Pico and other RP2040 boards via Web Serial API. Write code in the browser (in JavaScript), then copy and run it on the board with a click of a button.
Based on JerryScript, the creators also provide an IDE and serial communication tool on their website. There's also ample documentation and guides. Looking forward to getting more into this.

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

Txiki.js: Tiny JavaScript runtime built with QuickJS and libuv
Fitbit uses Jerryscript in some of their watch OSes. Well, at least they were last time I was tinkering with making my own watch face

Can you make your own JavaScript by implementing ECMAScript standard?
Indeed. ECMA-262 has been implemented using JavaScript https://github.com/engine262/engine262.
-
What sorts of things would you consider to be “advanced” javascript concepts?
Node.js is not the only JavaScript runtime. JavaScript runtimes have been written using JavaScript alone, see engine262. There is also Deno, QuickJS, txiki.js, Bun, none of which use COmmonJS by default, SpiderMonkey, et al.

Ask HN: What interesting problems are you working on? ( 2022 Edition)
for an interpreted language like JS, this project is really nice https://github.com/engine262/engine262. More or less 2 parts: parser and evaluator
-
Is there a source that shows how built in js methods/functions are built?
That is a bit complex, so here's a list of JS engines: if you pick one written *in* JS, that would probably be most useful -- engine262 for example

then you might be impressed by https://github.com/engine262/engine262 as well

And so was the C compiler.

[AskJS] is there a way to quantitatively check if a number value is copied or only the pointer to that number is copied?
It's outside of what you asked for, but here's a JavaScript engine in JavaScript. Might make for some interesting bedtime reading!
