HTML comments in a javascript block?

Hello im cleaning a web page from comments and other stuff.

I just found this <!-- but i dont understand why start with <!-- and close with -->

I use that to comment out something on html.. but here?? look at it

<script type="text/javascript"><!--
$("ul.menubbcl").superfish({        
    animation: {height:'show'},   // slide-down effect without fade-in 
    delay:     1000,           // 1.0 second delay on mouseout
    autoArrows : true 
}); 
//--></script>

    To support very old browsers which would render the script as text in the page rather than execute it. Commented Jan 14, 2013 at 2:38

  • Funny thing: the snippet uses jQuery, but I don't think even jQuery supports such old browsers (although it probably degrades gracefully). Commented Jan 14, 2013 at 2:40
  • Wait, doesn't this will create a SyntaxError for <!--? Commented Jan 14, 2013 at 2:48

    @Jeff - I tried window;<!--;window; and it comes out ok, so I guess the browser just ignores it. Commented Jan 14, 2013 at 3:29

This is for browsers that do not support Javascript. Supplying HTML comment tags around it will prevent it from being rendered as text in such browsers.
