ok so how it works is first the client ping the server

the server adds the client to the room

the client then can send msgs to the room thats it

so the client can only do emit events

and they can listen on other events

the stuff they listen can have like extra parameters depending on the event so thats how data is passed

for my example server side

• use node index.js to start the example

for my example client side

• use the get id to see the id
• then click joinRoom1 to join room1
• then click sendRoom1 to broadcast msg to room one
