title: How do you retrieve this value from chrome.storage?
body: <p>I'm a real noob to Javascript/JSON, so this might be really obvious. I'm storing values to chrome.storage in a chrome extension JS file: </p>
  
  <pre><code>chrome.storage.sync.set({'username' : username}, function() {
      console.log('Saved',username);
  }); 
  chrome.storage.sync.set({'password' : password}, function() {
      console.log('Saved', username);
  });
  </code></pre>
  
  <p>I know it's passed correctly because the console.log returns the right values. </p>
  
  <p>Then I try to retrieve it in my content script, but it only returns [object Object]. </p>
  
  <pre><code>chrome.storage.sync.get("username", function (username) {
      console.log("Passed successfully: Username "+username);
      studentUsername = username;
  });
  
  chrome.storage.sync.get('password', function (password) {
      console.log("Passed successfully: Password "+password);
      studentUsername = username;
  });
  </code></pre>
  
  <p>I'm not sure why it's doing this. </p>
