It seems that you are offput by his title in a way that you feel he is personally challenging your knowledge and experience with JavaScript. I would guess that when he was writing and naming this series, he did not have someone with 20 years experience in mind. Seems like the series is geared towards someone with moderate experience.

I don't think the title is the big issue here. I don't think it's good, and clearly it does put some people off with its tone, but as you say, maybe at least some of those people aren't the intended target audience.

My stronger reservation is that these books have a lot of loose writing and give so much space over to asides or describing bad practices that someone who wasn't so experienced might still not know JS by the end, having missed the wood for the trees.
