Simply JavaScript is for first-time JavaScript programmers. The authors, Kevin Yank and Cameron Adams will teach you JavaScript basics from the ground up. You'll learn about popular JavaScript libraries that can ease your scripting headaches, as well how to achieve dozens of common tasks. Unlike other JavaScript books, modern best practices such as progressive enhancement, accessibility and unobtrusive scripting are used from the very beginning. All the code in the book is also cross- browser compatible and downloadable for free.
