Persistent Objects on the Server

So far we have seen 2 important concepts

1. State Sharing in Rooms

2. Sending a Single Message to a Client

Now let's talk about Persistent Objects. These are special objects that are stored on the server and do not 'belong' to any client like entities. They can be created room wise.

Anyone can Create, Edit, Delete these special objects because no one Client 'owns' it.

For example there is a ball on the server. Some client can join, move it around and leave. Then another client can join and move it starting from the same place the previous client left it.
