Query: Two thumbs up!

This book is the Holy Grail.I've read pretty much every other JavaScript / DHTML book out there, and this blows them all away.What sets this book apart from all the rest I've read, in my opinion, are the detailed sections on "Client-Server Communication", XML, and Web Services. Nicholas explains the XMLHTTP / XMLHTTPRequest objects, which enable web developers to create highly-interactive, useable web applications - much like "normal" applications.The chapter, "Deployment Issues" is outstanding as well. Zakas gives numerous performance tips, obfuscation techniques, and describes issues that may be encountered in different browsers.If you're looking for the latest and the greatest, this is the one.
