Limit the user on the number of messages in the chat by time?

Question

JavaScript

Chat on sockets from the example, you can send as many messages as you like in it. I'm wondering how you can programmatically restrict a user from trying to send a bunch of messages in a short amount of time. Of course, validation must be set on the server, namely index.js as from the example.

    // Не отправляем сообщение
    return false;
}
// Отправляем сообщение
messagesInfo[nickname] = Date.getTime() / 1000;
