What this book covers

Chapter 1, Getting Started with TypeScript, covers setting up an environment for developing TypeScript applications and creating a simple application.

Chapter 2, TypeScript Basics, covers the primary language features that TypeScript creates on top of JavaScript and how each of these features compiles into plain JavaScript.

Chapter 3, The TypeScript Compiler, examines the TypeScript compiler and the different parameters that it accepts. The results of the different parameters will be discussed as well as how they affect the final JavaScript output.

Chapter 4, Object-oriented Programming with TypeScript, is all about the basics of object-oriented programming. You will be presented with the benefits that TypeScript adds to make ECMA Script a more full-fledged object-oriented language.

Chapter 5, Creating a Simple Drawing Application, walks you through creating a simple drawing application using the concepts already covered in the book. By the end of the chapter, you will have created a web-based drawing application that will give you a good understanding of writing complex applications using TypeScript.

Chapter 6, Declaration Files and Library Integrations, discusses declaration files and how they help us integrate with other JavaScript libraries. Libraries such as jQuery, KnockoutJS, and RequireJS will be covered.

Chapter 7, Enhancing the Drawing Application, re-examines the drawing application and shows you how to create a more reusable set of objects. Module definitions will be created and the process of minifying code is covered.

Chapter 8, Debugging TypeScript, discusses the different options available to debug TypeScript once it is deployed and running. We also cover unit testing and test-driven development, which will allow us to test functionality with code.
