HTML <script> tag
Definition and Usage
Defines a script, such as a JavaScript.
Differences Between HTML and XHTML
The "language" attribute of the script element was deprecated in HTML 4.01.
The "language" attribute of the script element is not supported in XHTML 1.0 Strict DTD.
Tips and Notes
Note: Code within this element is executed immediately when the page
is loaded, if it is not in a function. Script that appears after a
<frameset> tag will be ignored.
