Overview of this book

TypeScript is both a language and a set of tools to generate JavaScript, designed by Anders Hejlsberg at Microsoft to help developers write enterprise-scale JavaScript. Mastering Typescript is a golden standard for budding and experienced developers. With a structured approach that will get you up and running with Typescript quickly, this book will introduce core concepts, then build on them to help you understand (and apply) the more advanced language features. You’ll learn by doing while acquiring the best programming practices along the way. This fourth edition also covers a variety of modern JavaScript and TypeScript frameworks, comparing their strengths and weaknesses. You'll explore Angular, React, Vue, RxJs, Express, NodeJS, and others. You'll get up to speed with unit and integration testing, data transformation, serverless technologies, and asynchronous programming. Next, you’ll learn how to integrate with existing JavaScript libraries, control your compiler options, and use decorators and generics. By the end of the book, you will have built a comprehensive set of web applications, having integrated them into a single cohesive website using micro front-end techniques. This book is about learning the language, understanding when to apply its features, and selecting the framework that fits your real-world project perfectly.

Summary

We have covered a lot of ground in this chapter. We started with a discussion on interfaces, and how they allow us to define custom types that can be used to better describe objects with their designated properties and sub-properties. We then moved on to discuss classes, and how to use the various TypeScript language features that are specially designed with classes in mind. This discussion included class constructors, class modifiers, readonly properties, get and set functions, and static properties and methods. We then discussed the ins and outs of class and interface inheritance. We took a look at the super keyword, and how it can be used within class constructors as well as class methods in a class hierarchy. We then discussed abstract classes, abstract methods, the protected access modifier, and instanceof. In the final section of this chapter, we discussed modules, and how breaking up a large project into multiple smaller files can aid with code structure. We showed...
