title: What is .tpl.html files? (angularjs)
body: <p>I'm doing a angularjs blog tutorial, in the code example I see this new file type "<strong>tpl.html</strong>":</p>
  
  <pre><code>$routeProvider
  .when('/', {
  templateUrl: 'views/post-list.tpl.html',
  controller: 'PostListController',
  controllerAs: 'postlist'
  })
  .when('/post/:postId', {
  templateUrl: 'views/post-detail.tpl.html',
  controller: 'PostDetailController',
  controllerAs: 'postdetail'
  })
  .when('/new', {
  templateUrl: 'views/post-create.tpl.html',
  controller: 'PostCreateController',
  controllerAs: 'postcreate'
  });
  </code></pre>
  
  <p>What is this file type? Is different to html files?</p>
