So first let us set up our html file to request for a username var app require.
Socket io private room.
Socket io provides a dynamic list of the rooms that each socket is a member of.
To leave a channel you call leave in the same fashion as join both methods are asynchronous and accept a callback argument.
In that case every socket in the room excluding the sender will get the event.
One thing to keep in mind while using rooms is.

Build real time chat rooms with node js and socket io duration.
These channels are called rooms.
Rooms also share the same socket connection like namespaces.
Rooms are used to further separate concerns.
In this recipe we will create a list of the rooms that our socket is in.
Each socket in socket io is identified by a random unguessable unique identifier socket id for your convenience each socket automatically joins a room identified by its own id.
Allows for private rooms where a key is used and storing data for a room.
The list will be dynamically updated if the socket leaves any of its rooms.
Within each namespace you can also define arbitrary channels that sockets can join and leave.
