<SCRIPT ...> designates a script section of the page. The contents of <SCRIPT ...> are run using the scripting language set by the required TYPE attribute. For example, the following <SCRIPT ...> sets a short JavaScript, by far the most common scripting language.
It is a popular but inaccurate belief that the LANGUAGE attribute is required for <SCRIPT ...>. In fact, LANGUAGE has never been a required attribute and has not been the standard way to indicate scripting language for several years.
<SCRIPT ...> elements should always begin with <!-- on the first line.
The last line should begin with the line-level comment string for the scripting language
(// in JavaScript) followed by -->, as in the example above.
