const messageInput = document.getElementById('message');
const messagesList = document.getElementById('messages');

messageForm.addEventListener('submit', (e) => {
    e.preventDefault();
    const message = messageInput.value;
    socket.emit('chatMessage', message);
    messageInput.value = '';
});

socket.on('chatMessage', (message) => {
    const li = document.createElement('li');
    li.textContent = message;
    messagesList.appendChild(li);
});
