CoffeeScript

CoffeeScript: Accelerated JavaScript Development offers a thorough introduction to this new language, starting from the basics. You’ll learn to use time-saving features like list comprehensions and splats, organize your code into modules with extensible classes, and see how to deploy your work to multiple environments. Each chapter is example-driven and includes challenging exercises to push your CoffeeScript know-how further.
Through the course of the book, you’ll build a fast-paced multiplayer word game‚ writing both the client (with jQuery) and server (with Node.js) in CoffeeScript. And because the two languages are so deeply intertwined, you’ll deepen your understanding of JavaScript along the way.
CoffeeScript makes it easier than ever to write powerful, standards-compliant JavaScript code. This book lets you start doing it today.
