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.

What can developer do with Emitter
Emitter provides a messaging pattern where senders of messages, called publishers, send messages to Publish-Subscribe channels. Receivers, called subscribers, each receive a copy of the message in real-time. This decouples sending and receiving, giving you all the advantages of asynchronous communication.
We have designed a system that can be distributed across the globe. The system is designed to handle millions of messages per second and to scale horizontally without any problems.
We have built the system with a dead-simple and easy to use API. The API is designed to publish, subscribe and unsubscribe from channels, and all other functionality is built using that same API.
The entire system is designed to ensure speed-of-light message delivery. Whether you are building a web application, a dashboard, an online game or a connected car application, we ensure the fastest possible communication.
The system supports a distributed message filtering where a subscriber wishes to receive only a subset of messages, lowering the bandwidth requirement and overall design complexity of applications.
Published messages can be stored for a period of time on our servers and sent to subscribers on-demand. This ensures that your applications will never miss a message, even if they were not connected when the message was sent.

๐๐ฝ 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.
