hexadecimal to string

[Jeevan25]

this is a javascript code:

<script language="JavaScript" type="text/javascript">var i,y,x="ab";y='';for(i=0;i<x.length;i+=2){y=y + unescape('%'+x.substr(i,2));}document.write(y);</script>

i believe that would output «.now when i browse the source code via a browser, i don't see the string but rather the hexadecimal code. i want to see the actual converted string that is stored in variable y. how do i do this? i dont know anything about javascript. pls help and thanks. ps: a challange from friend and wouldn't tell me the answer.
