title: node and express send json formatted
body: <p>I'm trying to send formatted json with express.</p>
  
  <p>Here is my code:</p>
  
  <pre><code>var app = express();
  
  app.get('/', function (req, res) {
    users.find({}).toArray(function(err, results){
      // I have try both
      res.send(JSON.stringify(results, null, 4));
      // OR
      res.json(results);
    });
  });
  </code></pre>
  
  <p>I get the json in my browser but it's a string.
  How can I send it so it's readable in the browser?</p>
