hex to string conversion algorith

[Jeevan25]

there are no forum for javascript so i am posting here.
a hexadecimal value is stored in a var name x.

using
y='';for(i=0;i<x.length;i+=2){y+=unescape('%'+x.substr(i,2));}document.write(y);

that can be output but without the showing the code in string. i want to get the string code. how do i do this? this is a challange i got from friend. more importantly, how do i just view the string code. i mean the that code translates but doesn't tell me. so what should i do? thanks in advance

i dont know anything about javascript.

not exactly sure what you are up to but document.write(x) writes the original string out
