title: 0 returns undefined in Live code
body: <p>I have this simple code,</p>
  
  <pre><code>var movieRecordID = $scope.moviesCheck.filter(function(x){
      return x.movie_id == $scope.movieListID.id;
  });
  $scope.lolMOvie = movieRecordID[0].id
  </code></pre>
  
  <p>This returns a object and stores it into a variable called <code>movieRecordID</code>. To get to the ID value inside the object I have to use <code>[0]</code>. </p>
  
  <p>Locally this works fine, but live it throws an error, </p>
  
  <blockquote>
    <p>TypeError: Cannot read property 'id' of undefined</p>
  </blockquote>
  
  <p>Any ideas why?</p>
