Events and Event-driven Architecture

EventEmitter Class

The EventEmitter class in Node.js facilitates event-driven programming by allowing objects to emit named events asynchronously. Developers can create custom events and define listeners to handle them.

Core Events

Node.js core modules, such as HTTP, File System, and EventEmitter, utilize event-driven architecture extensively. Understanding core events and their event emitters is essential for building Node.js applications.

A process object is a global object that gives information about and controls the node.js process. As it is global, it can be used in the project without importing it from any module.
