This is a book about dogma. My dogma. It is a set of principles, practices, and rituals that I have found to be extremely beneficial when building React applications. I try to apply these ideas in my daily work, and I believe in them so much that I take every opportunity to teach others about them. That’s why I’ve written this book: to show you the ideas that have helped me be successful in my own career.

As with any dogma, you are free to make your own mind up about it. There are people who will dislike everything about this book. There are those who will love everything about this book. Yet more people will absorb some things and forget others. All of these are fine. The only thing I ask is that you maintain an open mind while you follow along and prepare to have your own dogmas challenged.

Test-driven development (TDD) did not originate in the JavaScript community. However, it is perfectly possible to test-drive JavaScript code. And although TDD is not common in the React community, there’s no reason why it shouldn’t be. In fact, React as a user interface platform is a good fit for TDD because of its elegant model of functional components and state.

So, what is TDD, and why should you use it? TDD is a process for writing software that involves writing tests, or specifications, before writing any code. Its practitioners follow it because they believe that it helps them build and design higher-quality software with longer lifespans, at a lower cost. They believe it offers a mechanism for communicating about design and specification that also doubles up as a rock-solid regression suite. There isn’t much empirical data available that proves any of that to be true, so the best you can do is try it out yourself and make your own mind up.
