Running javascript libs from standalone players

Hello is it possible to call from a Stansalone player (eg. Windows or MacOS) into jslib files such as any lib converted with Emscripten?
My goal is to convert a few java libs into javascript using Emscripten and then make them usable in Standalone versions of the player.

Thanks

I end up using Jint
