title: JavaScript function to add X months to a date
body: <p>I’m looking for the easiest, cleanest way to add X months to a JavaScript date.</p>
  
  <p>I’d rather not <a href="http://www.codeguru.com/forum/showthread.php?t=458137" rel="noreferrer">handle the rolling over of the year</a> or have to <a href="http://www.vbknowledgebase.com/?Id=80&amp;Desc=Javascript-Date-functions-for-VB-DateDiff-DateAdd" rel="noreferrer">write my own function</a>.</p>
  
  <p>Is there something built in that can do this?</p>
