title: Discord.js: using Nicknames instead of Usernames
body: <p>I've used the beginner guides out there to get started on a simple bot for our guild discord. But, for the love of me, I cannot find a way for the bot to refer to server specific nicknames instead of usernames.</p>
  
  <p>The code looks somewhat like this:</p>
  
  <pre><code>bot.on('message', function (user, userID, channelID, message, evt) {
      if (message.substring(0, 1) == '!') {
          var args = message.substring(1).split(' ');
          var cmd = args[0];
  
          args = args.splice(1);
          switch(cmd) {
              case 'ping':
                  bot.sendMessage({
                      to: channelID,
                      message: 'Pong! was returned to user with nickname ' + ????????????.nickname
                  });
              break;
           }
       }
  }
  </code></pre>
  
  <p>Anyone know what the command/variable is to retrieve nicknames instead of usernames?</p>
  
  <p>Thank you so much in advance :)</p>
