    <p>The Promise object is used for deferred and asynchronous computations. A Promise is in one of four states:</p>
    <ol>
      <li><b>pending:</b> initial state, not fulfilled or rejected.</li>
      <li><b>fulfilled:</b> successful operation.</li>
      <li><b>rejected:</b> failed operation.</li>
      <li><b>settled:</b> fulfilled or rejected</li>
    </ol>

    <p>This demo gets a 'news feed' (see below) from <a href="data/feed.json" title="News feed data feed in JSON format">data/feed.json</a> using <a href="../xhr" title="Ajax (XHR) example">XHR</a>.</p>

    <p class="borderBelow">There's more information about JavaScript Promises in <a href="https://www.html5rocks.com/en/tutorials/es6/promises/" title="JavaScript Promises article">Jake Archibald's article on HTML5&nbsp;Rocks</a>.</p>
