title: Reverse order of items pulled from database in ng-repeat
body: <p>I have a 'photos' array in a MongoDB database that is updated as users take photos on Instagram at certain locations.
  I push information about each new photo to this 'photos' array, so the most recent photo is on the end of the array. This is where my issue arises.</p>
  
  <p>I use ng-repeat to display these photos in my view. The obvious problem is that the most recent photo ends up at the end of the page rather than the beginning.</p>
  
  <p>What is the easiest way to reverse the order ng-repeat displays in? I have not been able to find a built-in filter that does this.</p>
