Lua is perfect for Redbean because it's tiny and made for embedding, which is this exactly use case. Something like TypeScript would require a transpiler to JS and a JS runtime, which as far as I know, even the smallest one would be much bigger than Lua. And Lua has well defined semantics to call C and be called by C, which may be hard to do with JS/TS.

Any examples and good tutorials on how to best go about it?

Best go about using Redbean? The project is well documented: https://redbean.dev/

Just go through it, it answers all questions you may come up with IMO.

Or you mean about embedding Lua? The official docs are great too: https://www.lua.org/pil/24.html

If you prefer a tutorial, there's plenty as Lua has been around for a long time. Search on Youtube for example and there's lots of videos.

The top hit on DDG for me was https://lucasklassmann.com/blog/2019-02-02-embedding-lua-in-... which seems pretty straightforward to follow.

quickjs [1] has native support for Cosmopolitan, is meant to be easily embeddable, and is included as part of the standard Cosmopolitan distribution. It looks like qjs also has patches for recent-ish versions of the Typescript compiler as well. Someone has made a nodejs-style project called txiki.js [2] using vanilla qjs. Maybe it would build with Cosmopolitan with some tweaking. But if you're thinking of packaging a whole browser engine like Electron that might be a Sisyphian effort.

I would suggest iced if you're ok with Rust https://github.com/iced-rs/iced

It's amazing, but I should warn documentation right now is not quite thorough
