I've been using JS "seriously" for many years, and only decided to try CoffeeScript out in my latest project which is on Rails 3.1 - so using CS was effortless. The transition was very easy, and the syntax is much more readable - that was enough to sell me. Going on, I also found myself starting to organize my code better with the use of CS classes. I still appreciate the idea of JS classless objects, but having a convenient syntax had a good influence on my code organization (at least for now).
