I maintain a library for using QuickJS, a JS interpreter with more modern language support, from NodeJS or the web called QuickJS-Emscripten: https://github.com/justjake/quickjs-emscripten

This was inspired by seeing Duktape WASM build on HN (https://github.com/maple3142/duktape-eval) and Figma's blogposts about building a Javascript plugin runtime:

- How Figma built the Figma plugin system: Describes the LowLevelJavascriptVm interface (https://www.figma.com/blog/how-we-built-the-figma-plugin-sys...)

- An update on plugin security: Figma switches to QuickJS (https://www.figma.com/blog/an-update-on-plugin-security/)
