In this chapter, we will cover the following recipes:
Socket.IO uses namespaces to keep separate types of messages from colliding with each other. With namespaces, we can be sure that our applications are listening for the correct events.
We can also define arbitrary rooms that our sockets can join or leave. These rooms restrict someone from receiving messages and send them only to interested parties.
In this chapter, you will also learn how to harness namespaces and rooms to create richer real-time experiences.
