  1. Hello!
    in your example:

    myEmitter.on(‘ping’, function (data) {
    console.log(‘First event: ‘ + data);
    });

    myEmitter.emit(‘ping’, ‘My first Node.js event has been triggered.’);

    What’s the difference of doing:

    function ping(data){
    console.log(“First Event: ” + data)
    }
    ping(‘My first Node.js event has been triggered.’)

  2. The difference in the two scenarios you listed is when you use Events your functions are fired in response to an event while simply calling a function means the functions are fired almost immediately.

  3. The difference is that anytime that event is triggered asynchronously, the event handler prints out the data sent to it. The event handler can do anything like send new signup email or subscription reminder emails. The event can be triggered multiple times as long as the app is running.
