While it is still in the early stages and not ready for prime time, you may want to take a look at Static Hermes, a JS engine that can AOT compile to native code. It is an evolution of Hermes, an already impressive JS engine that AOT compiles to bytecode and is jitless.
This is a good talk about it here:
I made an initial POC with raylib, GitHub - thejustinwalsh/sh-raylib: raylib bindings for static hermes, but this repo may have attrophied as I have not kept up with head on the static hermes branch.
And finally the community thread: How to try Static Hermes · facebook/hermes · Discussion #1137 · GitHub
Initial typescript support is there but needs a little improvement.
C# seems like a more stable and complete implementation, and the ex-unity crowd is a welcome addition for sure.
When the APIs stablize for an additional community scripting language support, I would be happy to take a crack at bringing Typescript/Javascript along for the ride. Static Hermes essentially has a zero cost FFI, and I imagine the work required to get C# working and marshalling over a C ABI would allow me to quickly implement the static hermes bindings / support.
