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.

Up and Running Quickly

So, what exactly is TypeScript? And how can we use it? Well, it really is as simple as "TypeScript generates JavaScript", to quote Anders Hejlsberg, the designer of the TypeScript language. Wherever we see a use for JavaScript in the modern world, we can generate this JavaScript using TypeScript.

JavaScript is being used everywhere – the more you look, the more JavaScript you find running in the most unlikely of places. Just about every website that you visit is using JavaScript to make the site more responsive, more readable, or more attractive to use. The power and flexibility of JavaScript also means that more and more tools are moving on-line. Where we once needed to download and install a program to write a document, or draw a diagram, we can now do this all from within the confines of our humble web browser.

The popularity and simplicity of JavaScript has inspired a whole host of runtime environments that can now run on a server...
