Take a look at the diagram at the bottom of http://www.sohamkamani.com/blog/2017/03/31/react-redux-connect-explained/

Still the best explanation of what does connect do!

IMHO, It might help the book to show something like that

That's one good looking diagram! I agree that something like this would be helpful - we'll see what we can do in the next update. Thanks for the tip!
