Why doesn't socket.io transfer work?

Question

Node.js

Hello!
I started to study socket.io, I ran into this problem:
The site has a form (input text + button). The user enters text and sends a message to the chat
Using PHP, user data (login, link to avu, id) is substituted into the script code.
The code on the client is:

..........

// Отправка сообщения при клике
$('#send-btn').click(function() {
  var message = $('#message').val();
  var username = '<?=$user['personaname']?>'; 
  var avatar = '<?=$user['avatarmedium']?>';
  $('#message').val('');

  socket.emit('new message', (username, message, avatar));
});

// Получаем сообщения (для начала пытаюсь просто в консоль вывести значения)
socket.on('new message', (username, message, avatar) => {
  console.log('Message from: ' + username);
  console.log('Message: ' + message);
  console.log('Ava: ' + avatar);
  console.log('_____________________');
});

..........

Server code:

socket.on('new message', function (username, message, avatar) {
  console.log('new message');

  io.sockets.emit('new message', (username, message, avatar));
});

But for some reason it gives the following in the console:

Message from: null
Message: undefined
Ava: undefined

Tell me what am I doing wrong?

Yes, because only an object with variables (one parameter) should be transferred. Just pass in an object (you can call it pocket) and set the object's properties to username, message, avatar. And to get values ​​like this: pocket.username ...
