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.

What is NativeScript?

NativeScript is the open source framework for building native Android and iOS applications with web technologies. This means we can develop native mobile applications with JavaScript, TypeScript, and/or Angular. NativeScript is based on the thinking of write once and run everywhere.

Applications developed with NativeScript are pure mobile apps when compared to applications developed with technologies such as PhoneGap. As they are native mobile applications, we can use all the richness of the mobile platform and provide the performance associated with that. We use native APIs and use native controls to render, which allows us to create more sophisticated applications compared to a hybrid approach. Hybrid applications do not provide the same level of flexibility or performance because they are hosted on a separate framework and do not get to interact with...
