title: What's the simplest way to decrement a date in Javascript by 1 day?
body: <p>I need to decrement a Javascript date by 1 day, so that it rolls back across months/years correctly.  That is, if I have a date of 'Today', I want to get the date for 'Yesterday'.</p>
  
  <p>It always seems to take more code than necessary when I do this, so I'm wondering if there's any simpler way.  </p>
  
  <p>What's the simplest way of doing this?</p>
