How does event emission work in Socket.IO?
In Socket.IO, event emission allows you to send messages between the client and server. You can emit events with data.
Can you give me an example of emitting an event?
Sure! On the client side, you can use socket.emit('eventName', data); to send data. On the server, you listen with socket.on('eventName', callback);.
What happens if the event is not handled on the server?
If the event is not handled, the emitted data will be ignored, and no response will be sent back to the client.
Is it possible to emit events to all connected clients?
Yes, you can use io.emit('eventName', data); on the server to broadcast an event to all connected clients.
