While we came a long way in this chapter, maybe Facebook doesn't have anything to fear from the baby steps we took toward converting the Notes application into a social network. This chapter gave us the opportunity to explore some really cool technology for pseudo-real-time communication between browser sessions.
In this chapter, you learned about using Socket.IO for pseudo-real-time web experiences, using the EventEmitter class to send messages between parts of an application, jQuery, AJAX, and other browser-side JavaScript technologies, and avoiding page reloads while making AJAX calls.
In the next chapter, we will look into Node.js application deployment on real servers. Running code on our laptop is cool, but to hit the big time, the application needs to be properly deployed.
