WebSocket Implementation Node

With webSocket, we have a persisent connection, which means the client connects to the server and stays connected for as long as it needs to!
It is a seperate protocol from HTTP.
Its a two directional connection meaning one client sends a message to the server, now the server sends this new message to the other clients connected to the same server. This gives the Real time scenario of the chat applications.
User Room functionality to join and chat with your buddies.
Share your current location with your buddies.

socket.emit -> sends event to specific client

io.to.emit -> sends event to everybody in this room (configure the 'to')
socket.broadcast.to.emit -> sends event to all the clients in that specific room, limiting the user himself
