If you are interested in learning CoffeeScript, you may be interested in a free book called Smooth CoffeeScript.
The current version of the free book is 230 pages and broken out into various parts:
- Preface
- Language
- Introduction
- Basic CoffeeScript
- Functions
- Data Structures
- Error Handling
- Paradigm
- Functional Programming
- Searching
- Object Orientation
- Regular Expressions
- Modularity
- Appendix
- Language Extras
- Binary Heaps
- Performance
- Command Line Utility
- Reference and Index
I haven't personally read the book, but it looks like a lot of care, thought, and hard work went into writing it. If you are looking for a new book on CoffeeScript, give Smooth CoffeeScript a try.
On a related note, you may also be interested in my review on CoffeeScript: Accelerated JavaScript Development as well as another free online book on CoffeeScript, called The Little Book of CoffeeScript.
Don't forget the Try CoffeeScript Chrome Extension for practing your CoffeeScript from the convenience of your browser.
