Pre-Publication Reviewer Testimonials

“One of the best introductions to JavaScript.”—Raymond Wisman, Indiana University Southeast

“Cements the browser as a first-class development platform.”—Johnvey Hwang, Splunk, Inc.

“Excellent for learning to develop standards-compliant web applications.”—Paul Vencill, MITRE, Inc.

“The CSS chapter is compact, concise and full of useful info!”—Billy B. L. Lim, Illinois State University

“A good introduction to the DOM; doesn’t trip over cross-browser incompatibilities.”—Eric Lawrence, Microsoft

“Exceptionally clear Ajax tutorial; best I’ve reviewed! Great solutions for the very cool type-ahead and edit-in-place Ajax features. ‘Libraries to Help Eliminate Cross-Browser Compatibility Issues’ is fantastic. This book and your websites will be often-visited resources (if not best practices in themselves).”—John Peterson, Insync and V.I.O. Inc.

“I wish I’d had this when I was learning to program.”—Joe Kromer, New Perspective
