Stop losing time over Angular Change Detection

This book will learn you how Angular ticks, and contains tons of information that can't be found on the web. I had to reverse-engineer the Angular code-base to understand how Angular really ticks and wrote a book about it! Let's reverse-engineer the Angular source code together.

To be honest, I had never read a book that explained such a complex subject as Angular Change Detection with such ease as Brecht Billiet 's. 🙏 Strange fixes like setTimeout() or superfluous .detectChanges() calls will be a thing of the past.

I've been working with Angular since the early Angular.js days, and had a pretty good intuitive understanding of the change detection behavior. But this book managed to improve my mental model dramatically by putting all the pieces together in a clear and structured way, especially the in depth content about OnPush and its interactions. Highly recommended!

I've written these articles just for you!
