GreenCopperCmd

The green_copper_cmd project is a commandline JavaScript interpreter which uses the GreenCopperRuntime which is in turn based on quickjs.

For a list of features that work in script here you should check out the GreenCopperRuntime project.

#endif
console.log("path = $PATH");

Modules and fetch api
