title: Array with 2 indexes not passing a conditional test on it's first index
body: <p>Why is a <code>cont[key].config.classes</code> value of <code>["photo"]</code> passing this test when a value of <code>["photo", "title_caption"]</code> is not? </p>
  
  <pre><code>if (cont[key].config.classes[0] == "photo") {
      console.log('this array passed: ' + cont[key].config.classes);
  }
  </code></pre>
