I think this is more for someone already familiar with the foundation level than for a beginner

The irony of a book called "You Don't Know JS" not in fact intended for people who don't know JS. :)

Idk, I always interpreted it as a conversation, where you the reader are saying "I know javascript" and Kyle Simpson says that you don't, which is how the book is intended.

I've taken a few of his online courses and he does an excellent job telling someone they don't know js, without coming off arrogant. I think it's mostly because he can explain most issues in depth but as a previous comment pointed out, it isn't really a beginner series. Although, I am not sure "[learning] javascript" necessarily means that the learner is completely inexperienced.

I get the understood meaning - I was just making a joke. :)

This series of books took me to the next level in my career as a developer

I love books in markdown. I can read it with emacs, and automatically ferry the code snippets to a javascript buffer.

I wish more authors would publish the markdown or asciidoc. I'd pay for it.
