Depends on what you need, you have a couple of choices, you can do:

"".replace("www.", ""); //this will replace the first occurrence of "www." and return ""

"".slice(4); //this will slice the first four characters and return ""

"".replace(/^(www\.)/,"");  //this will replace the www. only if it is at the beginning
