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.

Chapter 5. Classes in CoffeeScript

We're going to change gears for a bit in this chapter. We've been learning details of the CoffeeScript language and putting them to work in our pet store application. In this chapter, we'll take a step back and learn about a big concept: classes. We won't be working on the pet shop application in this chapter—instead we'll use small self-contained examples to explore how classes work. We haven't forgotten about the pet shop, though, and classes will certainly come in handy when we return to it!

In this chapter, we'll learn:

  • What a class looks like in CoffeeScript

  • How to attach functions and properties to it, and how to use them

  • How to use inheritance to build powerful class hierarchies

  • How all of this translates to clean, sensible JavaScript
