I'm the author.<p>Writing about CoffeeScript has been a great experience. I'll continue to spread the word about the language with articles, conference talks, and perhaps screencasts—stay tuned.<p>It's worth mentioning that this is also the first book in print to offer substantial coverage of Node.js. I'm pretty happy about that. It's really, really cool to be able to write both the front and back ends of an app in the same language.
