title: Option issue using chrome.storage.sync.get for first time user
body: <pre><code>chrome.storage.sync.get('savedItem', function (result) {
  
      //some if else condition for result.savedItem here
      myResult = result.savedItem;
      });
  
  $('p').val(myResult);
  </code></pre>
  
  <p>With above code, I got an undefined, <strong>because there is no setting been saved in my options page for the first time user</strong>. I tried to set a default value to myResult like <code>if(result.savedItem == undefined) myResult = '';</code> but I still got undefined. Why?</p>
