Approach to managing users in socket.io in Node.js

First, it is important to note that when a new socket is created, it is assigned a unique Id which is retrieved by calling socket.id. This id can be stored within a user object and we can assign an identifier such as a username. For the front end, we will use React, and for the back end node.js and express. Create two folders in your main directory name server(backend) and client(frontend). Socket.on will be an event that will be called whenever needed, and the event is called by the socket.emit, where we call the event and pass the parameter if needed.

Socket.IO is a library that enables real-time, bidirectional, and event-based communication between the browser and the server. Managing users in Socket.io and Node.js typically involves handling user connections, disconnections, and broadcasting messages to specific users or groups of users
