Hi everyone, author here, this is proof of concept how lightweight JS/ES2020 engine called QuickJS and lightweight GUI toolkit FLTK can be used to build multi-platform desktop applications. In next videos, I will show how to automatically wrap whole CFLTK/FLTK definitions, so they can be used more user-friendly than raw wrappers as presented in video. Anyway, I hope you enjoy. I also marked segments of videos, so you can jump to interesting topics.

Really cool!

Is there an advantage to creating a quickjs wrapper instead of compiling the C wrapper into a node module?

This is my personal taste. QuickJS is simpler and more lightweight than Node/V8. Some developers like me prefer software they can comprehend. No JIT, small code base, clean code, easy to extend. With QuickJS I think I can build anything. Author of of QuickJS has long track record. Again, that is my personal taste.
