嗨，帮派，在此WebSockets教程中，我将向您展示如何向每个客户端广播消息，除了最初向服务器发送消息的客户端。这与从服务器发出消息相反，后者从服务器发出消息到每个单个客户端，包括最初发送消息的客户端。

  9. Another awesome tutorial from Shaun. When he has 10 million subscribers, I'll be able to say "I was watching him when he only had 300,000!" 🙂

  10. If you want to send chat by hitting the 'enter' key…

    let emitChat = function() {
    socket.emit('chat', {
    message: message.value,
    handle: handle.value
    });
    message.value = '';
    }

    // emit events

    btn.addEventListener('click', function() {
    emitChat();
    });

    message.addEventListener('keydown', function(event) {
    if (event.keyCode === 13) {
    emitChat();
    };
    });

  21. Thank you so much Net Ninja, is there any particular reason why you're still using old school javascript though? (non arrow functions/var)??
