    Can someone explain how the beginning and end of the html5shim script works?

    the script starts with /*@ and ends with @*/like this:

    /*@cc_on(function(a,b){function ........ (this,document);@*/

    What is the /*@ @*/ doing?

    I would expect the /* */ sequence to ment out all lines in between them, but since the script executes, that cant be the case here? I'm confused.

    Reset to default 15

    IE's JScript supports ‘conditional pilation’, a trick of hiding special browser-specific information in ments. The idea is that /*@...@*/ is such an unusual sequence of characters that it is safe to repurpose it to introduce this new syntax-level feature.

    html5shiv uses it to create a piece of code that won't even try to run on most browsers (which, like you did, will interpret the whole thing as a mend), but which has special meaning to IE.

    MS doc here. No other JS engine supports this. Typically you might favour more explicit behaviour-sniffing code instead, but if you really need to detect an IE feature that doesn't expose itself to sniffing otherwise, it can be handy.

    It's an IE-ism for "conditional pilation": http://www.javascriptkit./javatutors/conditionalpile.shtml
