Script

The   element links to or encloses source code of a given  such as "text/javascript" (JavaScript, the default but included for compatibility with older browsers), which operates on the containing HTML document. Other languages such as VBScript, which is only compatible with Internet Explorer, may be used by specifying the appropriate MIME type in the  attribute. But no practical purpose currently exists to do this, as JavaScript works in all the same browsers and more.

Optional attributes
Values listed in (parentheses or round brackets), separated by &#124; (pipes or vertical bars), are for enumerated attributes; the bold value is the default.
