I started reading this book due to my trust in the Manning editorial and was I wrong.

There are loads of edition errors where, for instance, the explanation of a code block refers to columns while the code is about rows.

Many code examples are pointless. The example about forms is awful. There are two text fields, one of them is always ignored and by the end of the chapter the author says "I don't actually care about the state. I only included it for an extra example". Man, if a part of code is dead please get rid of it.

I don't really blame the author, this is his first book. I'm appalled by the editorial team at Manning for allowing this to be published in this form.
