I don't know if this is true for CoffeeScript, but sometimes an unfamiliar syntax enables something new and very useful. You won't experience that unless you embrace something very different.

eS6 will have fat arrows, but comparing CS today to JS today, I find the -> and => constructs are more than just an abbreviation, they make it radically easier to write AND READ code that makes heavy use of functions.

YMMV, of course!
