title: Javascript string scanner?
body: <p>I'm wondering, is there any way to scan a string in javascript.</p>
  
  <p>e.g, I've got a string <code>abcdefdfdfssdfdssdffdq="HELLO"fdndkjdsnkjdnlkdfns</code> I'd like to scan that string and delete the characters between q=" and " and replace it with <code>GOODBYE</code> is this possible?</p>
