Mastering TypeScript - Fourth Edition

By: Nathan Rozentals

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.

This has been a fast-paced introduction to what TypeScript is, and what it can do for JavaScript development. We started by setting up a simple development environment, got the TypeScript compiler installed, and started to use it to generate JavaScript. We then took a look at the basics of the type system, and explored how types can elevate the development experience. Finally, we used a third-party JavaScript library with the help of the declaration files.

In the next chapter, we will take a closer look at the type syntax in a lot more detail, get to understand where and how to use the available types, and how the type syntax can be used in different ways when writing functions.
