EventEmitter

EventEmitter is a programming tool that allows different parts of a software application to communicate by sending and receiving messages called "events." When a specific action occurs—like a user clicking a button or data arriving—the EventEmitter "emits" or signals an event. Other parts of the program can listen for these events and respond accordingly. This approach helps organize code more efficiently by decoupling the components that generate events from those that handle them, making programs more modular, flexible, and easier to maintain.
