I really like the book, and Node.js. I am a fan of CoffeeScript as a better Javascript, so I am asking if anyone knows the state of a CoffeeScript compiler that supports the ‘Harmony’ extensions used in the book?

If you’re writing CoffeeScript, you don’t need to worry about the harmony flag. ECMAScript Harmony takes a bunch of good ideas from the broader JavaScript world (like CoffeeScript’s arrow function syntax) and pulls them into the spec.

So you shouldn’t need to do anything special to write your own CoffeeScript with respect to harmony in particular.
