I was wondering whether this book will cover CoffeeScript too?
Given the relationship between the two languages I'd definitely think it'd be good if it did, even if that just meant a chapter covering additional guidelines around CoffeeScript.
Thanks for writing us about this. The book doesn't cover CoffeeScript, but I'll pass your comment on to the editor.
Here's the book's current table of contents:
If you're looking for CoffeeScript info, you might check out The Little Book on CoffeeScript.
Thanks again for sharing this idea with us.
