Part I. Building Your Application
This book has three parts. In Part I, we start building web applications. We’ll be building and rebuilding a sample application titled Save The Child.
Note
We assume that you know how to write programs in JavaScript. If you are not familiar with this language, study the materials in the bonus online chapter first. You’ll find a fast-paced introduction to JavaScript there.
In Chapter 1 we’ll start working with a web designer. We’ll create a mockup, and will start development in pure JavaScript. By the end of this chapter, the first version of this application will be working, using hardcoded data.
Chapter 2 shows you how to use Ajax techniques to allow web pages to communicate with external data sources, without the need to refresh the page. We also cover JavaScript Object Notation (JSON)—a de facto standard data format when it comes to communication between web browsers and servers.
Chapter 3 shows how to minimize the amount of manually written JavaScript by introducing the popular jQuery library. You’ll rebuild the Save The Child application with jQuery.
After reading this part, you’ll be ready to immerse yourself into more heavy-duty tools and frameworks that are being used by enterprise developers.
