Greetings and thanks for your kind words!
Unfortunately JScript doesn't support ECMAScript 6, and that isn't likely to change in the future.
V8 on the other hand already supports some ECMAScript 6 features, and well-tested ones such as Promises are already enabled by default. Others, if supported, are probably not ready for general consumption, but you can enable them by modifying ClearScript. For more information, see here.
Good luck!
