How can I use decorators today?

I see decorators being used today already in some javascript code. My question is really two fold.


If decorators have not even been finalized how is it possible to use them in production code, today? Won’t browser support be non-existent?


Given it is possible to use it today, as some open source projects would suggest, what’s a typically recommended setup for getting decorators to work?
