Practical JavaScript for the Usable Web

Rating:
Summary: Great read
Review: A task oriented book that, notwithstanding a small number of pages, manage to break some new grounds and cover a few advanced topics. Not suited for a complete programming novice, but if you have some programming experience and want an intelligent introduction it may be a great choice. Also recommended to JavaScript freaks looking for some refreshing material

Summary: Great read
Review: Fresh and enjoyable read. This book is a great companion to a solid Javascript reference after you have dabbled in some Client side scripting.

Rating:
Summary: Sloppy and unorganized
Review: The book gives a narrow introduction on JavaScript for an intermediate programmer, so it is cutting corners. Many of them, nuf said!

Summary: Very good but not for the absolute beginner
Review: This is the perfect book if you want to refresh the Javascript you learned some time ago, or if you've gone through some on line tutorials and would like to get the whole picture.
It's less than 400 pages, but packed with information. Very clearly written and easy to read. It explains a concept and shows you examples, pointing out where you could make mistakes and giving advice for best practice. For an absolute beginner though, I think it would be a bit too fast-paced - if this is your case try Paul Wilton's other book.
