I had two friends who both wrote separate books on JS. One early book on Angular and the other was about jQuery. Both had a hard time with the critical reviews they received on Amazon and it really dissuaded them from doing any more technical writing.

I love your approach and hope you keep writing and don't let the trolls get to you! Our industry needs more people who have this "soup to nuts" approach and take into account how nearly every language has changed dramatically over time.

Again, congrats and keep writing.
