What are namespaces in Socket.io? How they are different from rooms?

• From socket.io docs: "A Namespace is a communication channel that allows you to split the logic of your application over a single shared connection (also called “multiplexing”)".
• A namespace will be created by default when calling:

  const io = require('socket.io')();
  

• Custom namespaces can be created:

  io.of("/music").on("connection", (socket) => { //... });
  io.of("/movies").on("connection", (socket) => { //... });
  

• Rooms are different from namespaces: they are arbitrary channel that sockets can join and leave and they are created under a specific namespace.

Let us know how you could utilize websockets in your project.

• My project is about video games review forum. Websockets can be applied to implement a real time review feed at the home page, where the newest reviews will be automatically added to the top of the feed.
