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.
