   =item * js_escape()
   
   js_escape takes a string, string reference or hash reference,
   and escapes the values so that they can be used within a <script> element.
   It replaces all instances of \ by \\, ' by \', " by \" and \n by \\n.
   It is typically used with localized strings, which might contain quotes.
