Overview of this book

TypeScript is a superset of the JavaScript programming language, giving developers a tool to help them write faster, cleaner JavaScript. With the help of its powerful static type system and other powerful tools and techniques it allows developers to write modern JavaScript applications. This book is a practical guide to learn the TypeScript programming language. It covers from the very basics to the more advanced concepts, while explaining many design patterns, techniques, frameworks, libraries and tools along the way. You will also learn a ton about modern web frameworks like Angular, Vue.js and React, and you will build cool web applications using those. This book also covers modern front-end development tooling such as Node.js, npm, yarn, Webpack, Parcel, Jest, and many others. Throughout the book, you will also discover and make use of the most recent additions of the language introduced by TypeScript 3 such as new types enforcing explicit checks, flexible and scalable ways of project structuring, and many more breaking changes. By the end of this book, you will be ready to use TypeScript in your own projects and will also have a concrete view of the current frontend software development landscape.

Summary

In this chapter, we discovered many new things.

First of all, React, one more hugely popular solution for creating modern web applications. We saw that even though it looked kind of intimidating at first, we could really quickly get started using CRA and no configuration at all, and with a minimal amount of code.

We learned about JSX and how enabling it can leverage the power of JavaScript while defining components. Of course, the syntax feels a bit alien at first for anyone used to separating templates and logic, but on the other hand, we showed that JSX helps to really take advantage of our JavaScript/TypeScript skills instead of having to learn a lot of new syntax!

We saw how to write React components using classes but quickly switched to the more idiomatic functional style that the React community loves. While doing so, we saw that it enabled us to write very concise...
