CoffeeScript seems to be doing well, they're working on version 2.0 (currently in alpha) aka coffeescript@next [1] with async/await (with similar approach as they did with generators where only `yield` keyword is used and the function is implicitly lifted to generator, similarly using `await` implicitly lifts function to async, so there's no need to mark function as async explicitly - very good idea IMHO), ES2015 classes and some other changes. CoffeeScript is still what it was before - making code easier and more pleasurable to read and write: less verbose, everything is an expression, existential operator, better switch, comprehensions, prototype access operator, chained comparisons, block regex, implicit returns, range loops...
