JavaScript, etc. This is still a work in progress, but it's pretty good for

to your searches).

JavaScript Allongé This book begins with a different approach to teaching common concepts. Overall, it is very focused on functional JavaScript. It does have an academic feel at times, but is also very focused on practical usage of the language. Depending on your learning style, it could be helpful or you may find it to be confusing.
I learn best by doing rather than reading, so please note that I have only paged through most of these books. I'm sharing my thoughts from the little time that I spent with each book in hopes that it helps expedite your search. I would suggest reading reviews on Amazon and/or paging through the book yourself at Powell's to make sure the book matches your learning style and expectations.

Learning Node, Shelley Powers Intermediate, $35 This is a pretty in depth look at various parts of Node.js and frameworks that are built with Node. This books was written early in the lifetime of Node.js and may be slightly inaccurate because of that, but still covers details of up to date tools. Node.js in Action may be a better choice, but this has material that complements the other as well.

Functional JavaScript, Michael Fogus Advanced, $30 This is an advanced book that gives good examples of advanced usage of functional programming concepts. It's a book that may cause your head to spin at times and sometimes has confusing explanations of concepts because it dives into each idea quickly. This book gives academic details on concepts like scope and closures.
