Definitely a +1 for ES6 support. ES6 has so many of the features that made Coffeescript a great alternative to the Javascript of old. The syntax for Coffeescript has a nicer aesthetic IMO, but I would prefer to write prototype code using the same syntax I write my production application code in, as one less context switch is always a huge win. There is also so many great (and free) resources on the web for learning ES6.
+1 for ES6 support. Especially if Framer 5 is going to adopt Preact, I prefer sharing a consistent abstraction with my developers (we do almost all of our apps on React now).
