Node JS Not Broadcasting To Sender

I'm starting the beginning of a two player game node js app and I'm trying to get the client/server working with nodejs. The issue is when I broadcast the message with socket.io it goes to all connections but not the sender. I can't figure out why socket.broadcast.emit would not broadcast to the sender.

If you want to broadcast the message to all connections you should use io.emit
