Hour 20. Working with Multimedia and Plug-Ins

Welcome to the last hour of Part V. In the last three hours, you've learned some of JavaScript's most advanced features: style sheets and the Document Object Model (DOM). In Hour 20, you'll learn another advanced feature: using JavaScript with plug-ins.

Plug-ins are browser add-ons that allow you to use additional types of information in the browser: sounds, videos, and so forth. You can use JavaScript to control the behavior of these plug-ins, allowing your scripts to do just about anything.
