I did have lengthy discussions with my book editor about the title and its potential to be off-putting to some. We wrangled with the decision awhile, but ultimately came to the conclusion that most would find it a mix/balance of playful, attention grabbing (in a sea of "JS: The Handy Guide" type titles), and challenging.
The title itself is supposed to be equal parts a joke and a serious commentary on what I consider to be a disturbing trend in JS specifically, which is either a false sense of confidence or (worse) an apathy to not care about what is not known.
Again, thank you for your thoughtful response and your feedback. I do regret that it's hit you the way it has. Perhaps at some point you may give it another shot.
