Scripts are little programs that add interactivity to your page. Because scripts are perfect for moving elements, they are the backbone of dynamic HTML (DHTML).

• Calling an external automatic script
• Triggering a script
• Creating a button that executes a script
• Hiding scripts from older browsers
• Adding alternate information
• Setting the default scripting language
