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 2. Writing Your First Lines of CoffeeScript

In this chapter, we will dive into CoffeeScript headfirst. We'll look at all the simple data types and control structures, and find out how CoffeeScript helps us deal with them more simply and expressively. We'll discover some neat tricks that save us keystrokes and reduce the likelihood of errors in our code. And we'll peek under the hood to see how some of the CoffeeScript magic is happening.

In this chapter, you can expect to:

  • Learn CoffeeScript syntax for many common operations

  • Learn how to use standard data types and control structures in CoffeeScript

  • See how the CoffeeScript we write maps back to JavaScript once compiled
