The aim of Sams Teach Yourself JavaScript in 21 Days is to tutor the Web-literate novice JavaScripter through to a high level of competency in applying JavaScript to Web pages.

In addition to core uses of client-side JavaScript, Sams Teach Yourself JavaScript in 21 Days also covers emerging topics such as the use of JavaScript with PDFs and the scripting of Scalable Vector Graphics (SVG).

The key principles taught throughout the book are backed up with clear and useful examples. This enables the reader to easily apply what theyve learned with confidence in order to meet their own coding needs.
