<!--//--><![CDATA[//><!--
some js here
//--><!]]>

A:
They were used for old browsers which didn't understand the <script> tag. That way if a browser didn't properly read the JavaScript, it would just render it as a comment and not show up on the page.
It also allows JavaScript code to be inside valid XHTML pages without having to escape characters which aren't valid in XML.

Are there any browsers left that still actually need it?

I was trying to think about that. Not that I know of, but I suppose you could still run into someone who uses it....not that it would (most likely) render any modern page today though.

@Williham Totland true enough, I have updated the answer to add that in.

A:
<![CDATA[//> is to prevent XML parsers from choking on the script.
<!-- ... --> is not required unless you're using Netscape 1.0.
