Having worked on an embedded script engine that was JS-based at the time, this is exactly what we were doing. Basically the script host (C++ code) offered up specific sets of available objects to the engine that you could interact with and essentially trigger the C++ functionality from, passing in data, and such. It wasn't a fantastic experience at the time but luckily for us the stakes were pretty low as we were working on interactive mall map kiosk devices.
