io.emit vs socket.emit vs socket.broadcast.emit


Send message to one client, like New user come, we show him "welcome message" 
socket.emit('message', "Welcome user to our Chat Group");


Sending to all clients except sender 
socket.broadcast.emit('message', "New user i.e joy joined our chat group."); 


Sending to all clients in 'game' room(channel) except sender
socket.broadcast.to('game').emit('message', 'sending to all clients in 'game' room(channel) except sender'); 


Sending to sender client, only if they are in 'game' room(channel)
socket.to('game').emit('message', 'sending to sender client, only if they are in game room'); 


Sending to individual socketid
socket.broadcast.to(socketid).emit('message', 'sending to individual socketid'); 


Sending to all clients, include sender
io.emit('message', "sending to all clients, include sender"); 


Sending to all clients in 'game' room(channel), include sender
io.in('game').emit('message', 'sending to all clients in game room'); 


sending to all clients in namespace 'myNamespace', include sender
io.of('myNamespace').emit('message', 'sending to all clients in namespace myNamespace');


for emiting to specific clients
io.sockets.socket('for emiting to specific clients'); 


send to all connected clients 
io.sockets.emit('send to all connected clients');
