The book explains on a high level how React Native works, provides an information on the available components in regards to their native equivalents, and goes in details about the build and deployment process. It’s a good reading material providing practical examples in a form of several small apps. However, I was expecting a deeper explanation of the React Native bridge and the mechanism of rendering native components from the React Native ones. Also, I founded the book a bit outdated especially considering the availability of solutions like Expo which simplifies significantly the development and publishing processes.
