Overview of this book

React is an adaptable JavaScript library for building complex UIs from small, detached bits called components. This book is designed to take you through the most valuable design patterns in React, helping you learn how to apply design patterns and best practices in real-life situations. You’ll get started by understanding the internals of React, in addition to covering Babel 7 and Create React App 2.0, which will help you write clean and maintainable code. To build on your skills, you will focus on concepts such as class components, stateless components, and pure components. You'll learn about new React features, such as the context API and React Hooks that will enable you to build components, which will be reusable across your applications. The book will then provide insights into the techniques of styling React components and optimizing them to make applications faster and more responsive. In the concluding chapters, you’ll discover ways to write tests more effectively and learn how to contribute to React and its ecosystem. By the end of this book, you will be equipped with the skills you need to tackle any developmental setbacks when working with React. You’ll be able to make your applications more flexible, efficient, and easy to maintain, thereby giving your workflow a boost when it comes to speed, without reducing quality.

Using React for the first time usually requires an open mind because it is a new way of designing web and mobile applications. React tries to innovate the way we build user interfaces following a path that breaks most of the well-known best practices.

In the last two decades, we learned that the separation of concerns is important, and we used to think about it regarding separating the logic from the templates. Our goal has always been to write the JavaScript and the HTML in different files.

Various templating solutions have been created to help developers achieve this.

The problem is that, most of the time, that kind of separation is just an illusion and the truth is that the JavaScript and the HTML are tightly coupled, no matter where they live.

Let's see an example of a template:

  {{#items}} 
{{#first}}
<li><strong>{{name}}&lt...
