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.

One of the watershed moments in the story of the TypeScript language came when it was announced that the Microsoft and Google teams had been working together on Angular 2. Angular 2 was a much anticipated update to the popular Angular (or Angular 1) single-page application framework, which was written in JavaScript. The Google team that built Angular 2 originally proposed a new language named AtScript, which would allow Angular 2 applications to use newer ECMAScript 6 and 7 language features, and make the Angular 2 syntax cleaner and easier to understand. It was, in fact, intended for AtScript to run on top of TypeScript.

Following several months of collaboration, it was announced that all of the necessary features of the AtScript language would be absorbed into the TypeScript language, and that Angular 2 would be written in TypeScript. This meant that the providers of the language (Microsoft) and the consumers of the language (Google) were able to agree on the requirements...
