| JavaScript |
| |
| JavaScript is by far the most popular scripting language and can be included directly in XHTML documents. |
| |
JavaScript can:
- React to events such as a mouse-click
- Manipulate or move text
- Detect the browser in use
- Detect installed plug-ins
- Perform mathematical calculations
- Create pop-up windows
- Add scrolling messages in the browser status line
- Create interactive banners
- and more....

| For JavaScript to work as intended, the user should have a browser that supports JavaScript. Importantly, JavaScript must be enabled. JavaScript should be used to enhance the experience of the user; it should not be a pre-requisite in order to view a page. |
