Overview of this book

React 16 Essentials, Second Edition, fully updated for React 16, takes you on a fast-paced journey through building your own maintainable React 16 applications. React experts Artemij Fedosejev and Adam Boduch give you all the essentials you need to know and start working with React 16, in this new edition of the best-selling React.js Essentials title. You'll find the latest React 16 code updates, assessment of React Fiber, new coverage of Redux, and how to work as a modern React developer. The authors offer you their current assessment of React Fiber, and you'll soon be exploring React 16 hands on, creating your own single and multiple user interface elements with React 16. You'll then see how to create stateless and stateful components and make them reactive. You'll also learn to interact between your components and lifecycle methods, and gauge how to effectively integrate your user interface components with other JavaScript libraries. Delve deep into the core elements of the Redux architecture and learn how to manage your application and data persistence. Then go the extra mile with the Jest test framework, and run multiple tests on your applications and find solutions to scale without complexity. Today React is used by Facebook, Instagram, Khan Academy, and Imperial College London, to name a few. Many new users recognize the benefits of React and adopt it in their own projects, forming a fast-growing community. The speed at which React has evolved promises a bright future for anyone who invests in learning it today. Let Artemij and Adam bring you a brand new look at React 16 and React Fiber, and move your web development into the future.

The best code is the code that you don't need to write. In fact, one of our goals in this project is to write as little code as possible. You might not realize this yet, but React helps us achieve this goal. Not only it saves us time, but if we also decide to maintain and improve our project in the future, it will save us even more time in the long run.

When it comes to not writing our code, we can apply the following strategies:

  • Writing our code in a declarative programming style

  • Reusing code written by someone else

In this project, we'll be using both techniques. The first one is covered by React itself. React leaves us no choice but to write our JavaScript code in a declarative style. This means that instead of telling our web browser how to do what we want (like we do with jQuery), we just tell it what we want it to...
