Ratings and reviews

This book is such a fantastic resource and I'm shocked it was available for free. The site and book on Play cover React.js and Next.js design patterns in a great amount of detail. I especially loved the animations and runnable code examples that are available on the site. It was nice to see this project also stay updated over time as React feels like it's been in a fast moving place for the last few years. Do check out the rendering and performance patterns sections too. Some great nuggets.

This book covers a lot of complex topics (rendering patterns) in a super understandable way. Loved how practical the React guidance is.

I'm sure that it would be a fantastic book if it worked, unfortunately the google play version does not work, with many pages lost in an infinite loading wheel, even after fully downloading it (tried in two devices from different manufacturers)
