Hey, I've made pdjs, an external that executes JavaScript using V8 and tries to emulate Max's js object.
It lives at https://github.com/mganss/pdjs and is available through deken for x64-windows, x64-linux, and arm64-linux currently (x64-macos planned).
Most core functionality is there so a lot of code written for Max js that doesn't use any extra objects (like LiveAPI, Buffer, Dict, etc.) should run unchanged.
Please report any issues or missing features at GitHub.
