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/

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.

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

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

Elk: A low footprint JavaScript engine for embedded systems
6 projects | news.ycombinator.com | 22 Sep 2021

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

What are some alternatives?
