At the heart of JavaScript is a beautiful little language. Unfortunately, that inner beauty is clouded with awkward syntax and structure. CoffeeScript is a new way to write JavaScript, providing Ruby-like readability and a more expressive syntax. It compiles into standard JavaScript and works on all implementations without modification. CoffeeScript in Action is a tutorial that teaches how, where, and why to use CoffeeScript. It begins by quickly exposing readers to CoffeeScript’s new, but instantly-familiar syntax. Then, it explores programming challenges that illustrate CoffeeScript’s unique advantages. Language junkies will especially appreciate how this book takes idioms from other programming languages and shows how CoffeeScript makes them available in JavaScript.Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications.
