What can developer do with Socket.IO
the technology is open source. But self hosted.
In most cases, the connection will be established with WebSocket, providing a low-overhead communication channel between the server and the client.
Rest assured! In case the WebSocket connection is not possible, it will fall back to HTTP long-polling. And if the connection is lost, the client will automatically try to reconnect.
Scale to multiple servers and send events to all connected clients with ease.

👋🏽 About Realtime
Realtime programming is a type of programming where the programmer writes code that is designed to run as soon as it is invoked, without any delay. This is in contrast to most programming, where code is written to run at some later time, either when invoked by another piece of code, or when a certain event occurs.
Realtime programming is important for developers because it allows them to create applications that need to respond to events immediately, without any delay. This can be important for applications that need to interact with the user in real time, or that need to control hardware devices that can only be accessed in real time.
