Overview of this book

The TypeScript language, compiler, and open source development toolset brings JavaScript development up to the enterprise level. It allows you to use ES5, ES6, and ES7 JavaScript language features today, including classes, interfaces, generics, modules, and more. Its simple typing syntax enables building large, robust applications using object-oriented techniques and industry-standard design principles. This book aims at teaching you how to get up and running with TypeScript development in the most practical way possible. Taking you through two exciting projects built from scratch, you will learn the basics of TypeScript, before progressing to functions, generics, promises, and callbacks. Then, you’ll get to implement object-oriented programming as well as optimize your applications with effective memory management. You’ll also learn to test and secure your applications, before deploying them. Starting with a basic SPA built using Angular, you will progress on to building, maybe, a Chat application or a cool application. You’ll also learn how to use NativeScript to build a cool mobile application. Each of these applications with be explained in detail, allowing you to grasp the concepts fast. By the end of this book, you will have not only built two amazing projects but you will also have the skills necessary to take your development to the next level.

Summary

In this chapter, the focus was on learning some new concepts of TypeScript and Angular. We looked at functions, classes, and interfaces in TypeScript, and templates and interpolation in Angular. We enhanced the user interface of our application by adding headers and footers, and made our code more object-oriented by using interfaces and modifying the code structure in our class. At this time, you have enough knowledge to create web applications with TypeScript and Angular, apart from features such as making web service calls and routing.

In the next chapter, we will add more features to our Sports News Combinator application, including making a web service call to fetch the sports news. You will be reading about decorator patterns and how they are used in Angular; then, we will also learn about the HTTP module and routing in Angular.
