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:

  • How the value of this can change in a method body, and how to use fat arrows to get the behavior we want.

  • How to use memoization to save and retrieve the results of expensive computation rather than repeating it.

  • How to use options objects to clean up our method signatures and easily set defaults.

This chapter was a graduation of sorts. You're now extremely well-versed in the CoffeeScript language! You've learned almost all of the syntax, including some fairly advanced tools and tricks. The next few chapters are all about using CoffeeScript to accomplish more, better. First up is a very common paradigm in web development: dealing with asynchronous operations.
