I agree that the way scope works in fat arrow functions is better, and I'm honestly excited about most of ES6 (proper maps and sets alone are worth it to me).

I agree that the way scope works in fat arrow functions is better, and I'm honestly excited about most of ES6 (proper maps and sets alone are worth it to me). What does make me sad is that the old shit isn't going away. And not that it's not going away soon, but that, as far as we can tell, we're going to be teaching people about "this" for the rest of eternity. I get why Brendan Eich and others are scared of versioning javascript, but I don't think it's tenable to have to keep so many semantically dischordant features of the language around for decades.
