title: JavaScript Object.keys() method alternative for compatibility with IE8
body: <p>I'm getting in error when testing in IE8 that the Object method is not supported.  I'm using <code>Object.keys()</code></p>
  
  <pre><code>Object.keys(jsoncont).sort(function(a,b){
     return b.localeCompare(a)
   }).forEach(function(key) {
      var val = jsoncont[key];
  
     /* My code here */
   });
  }
  </code></pre>
  
  <p>Is there a good workaround for this method that is supported by IE8?</p>
