The proper way to use Javascript in HTML

Goal: We want browsers not supporting Javascript to ignore the script statemantes.

1. Javascript in HTML

<script type="text/javascript">
<!--
...
//-->
</script>

2. Javascript in XHTML

<script type="text/javascript">
<!--//--><![CDATA[//><!--
...
//--><!]]>
</script>

3. Works everywhere!

<script src="foo.js" type="text/javascript"></script>
