CoffeeScript Application Development

By: Ian Greenleaf Young

Overview of this book

JavaScript is becoming one of the key languages in web development. It is now more important than ever across a growing list of platforms. CoffeeScript puts the fun back into JavaScript programming with elegant syntax and powerful features. CoffeeScript Application Development will give you an in-depth look at the CoffeeScript language, all while building a working web application. Along the way, you'll see all the great features CoffeeScript has to offer, and learn how to use them to deal with real problems like sprawling codebases, incomplete data, and asynchronous web requests. Through the course of this book you will learn the CoffeeScript syntax and see it demonstrated with simple examples. As you go, you'll put your new skills into practice by building a web application, piece by piece. You'll start with standard language features such as loops, functions, and string manipulation. Then, we'll delve into advanced features like classes and inheritance. Learn advanced idioms to deal with common occurrences like external web requests, and hone your technique for development tasks like debugging and refactoring. CoffeeScript Application Development will teach you not only how to write CoffeeScript, but also how to build solid applications that run smoothly and are a pleasure to maintain.

In this chapter, we learned all about classes in CoffeeScript. We saw:

  • How to define and instantiate classes

  • How to attach properties and methods to classes, and how to call them internally with @

  • How to attach static properties and methods to the class object itself

  • How to use constructors to perform initialization for the class

  • How to use CoffeeScript classes in Ember.js and Backbone.js

  • How CoffeeScript implements all this using JavaScript's prototype system

Now that we know almost everything there is to know about CoffeeScript classes, we're ready to put this knowledge into practice. The next chapter is going to be all about using classes to create modular, maintainable, understandable code. We're going to return to our pet shop application and do some serious refactoring.
