title: Twitter id to screen name
body: <p>I have the following code to request a twitter user by ID:</p>
  
  <pre><code>request.get( {
      url: 'https://api.twitter.com/1.1/users/lookup.json?user_id=' + userIds,
      oauth: {
              consumer_key: 'KEys',
              consumer_secret: 'are',
              access_token: 'here',
              access_token_secret: ''
            }
     }, function (error, response, body) {
              if (error) {
                  reject(error);
              }
              var json = JSON.parse(body);
              console.log(json);
         }
  });
  </code></pre>
  
  <p>What do I do next to extract screen name of the twitter user?</p>
