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

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

I found a remote code execution bug in VSCode that can be triggered from untrusted workspaces. Microsoft fixed it but marked it as moderate severity and ineligible under their bug bounty program.

At the same time as studying the Rhino's source code, I downloaded its source files and ran the analysis using the PVS-Studio plugin for IntelliJ IDEA. The analyzer found quite a few warnings for a 25-year-old project (they are listed in descending order of certainty):

Best way to integrate Python and JavaScript?

I'm guessing it would be possible using Jython and Rhino, for one example, but I'm curious whether or not anyone's ever actually done this, and if there are solutions for other platforms (especially CPython).
