Scala is vastly different than Java. CoffeeScript is just "clean" JavaScript. You can (and I have done) convert a 200 LOC JS code to CS in less than 15-20 minutes and think carefully about every change you make. Java -> Scala is like re-architecturing your project. JS -> CS is more like re-factoring.
