WordPress is much more than a blogging platform. If you have basic PHP, HTML, CSS, and JavaScript experience you can use WordPress to develop fast, scalable, secure, and highly customized web apps, mobile apps, web services, and multisite networks of websites. Along with core WordPress functions and database schema, you’ll learn how to build custom plugins, themes, and services for just about any kind of web or mobile application.
In this updated second edition, Brian Messenlehner and Jason Coleman cover new features and functionality added to WordPress up to version 5.4. All code examples in the book are available on GitHub.

Quite informative but the project they took to explain is not updated to recent edition. The same code they used for first edition.
Overall a good collection of information about WordPress development but this book is not for novice as it's not a cookbook. You learn the concept but you have to DIY if you like replicate what they are saying.
This book is an easy read and covers a wide range of Wordpress topics, everything from building plugins to building mobile apps. It also has a ton of great plug-in and library recommendations.
