In JavaScript, an Event Emitter is a crucial part of reactive programming, facilitating flexible communication between different components of an application.
Building your own Event Emitter allows you to understand its workings deeply, fostering coding skills and enabling the creation of customizable applications.
Using Event Emitters enables decoupled communication, permitting components to interact without direct dependencies, thereby promoting reusability and scalability in applications.
To build your Event Emitter, you need to create a class that manages event listeners, and has methods like on(), emit(), off(), and once() to handle events.
