body: <p>I'm trying to get <code>share_count</code> data for page <code>https://graph.facebook.com/?ids=http://backlinko.com</code> 
  Here my code:</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div id='demo'/&gt;

    var fbsrc = "https://graph.facebook.com/?ids=http://universalmanual.com";
    var request = new XMLHttpRequest();
  request.open('GET', fbsrc, true);
  
  request.onload = function() {
    if (request.status &gt;= 200 &amp;&amp; request.status &lt; 400) {
      // Success!
      var data = JSON.parse(request.responseText);
      document.getElementByID('demo').innerHTML+=data.share.share_count;
    } 
  };
  
  
  
  request.send();
