Node.js Events EventEmitter Example From Scratch is today’s leading topic. EventEmitter is an implementation of Node.js’s pub-sub design patterns.

Node.js core API has built on the asynchronous event-driven architecture.

In an asynchronous event architecture, certain kinds of objects (called “emitters”) periodically emit named events that cause Function objects (“listeners”) to be called. Each object that emits events are instances of an EventEmitter class.

We are going to see one example with ES5 Syntax.

Node.js Events EventEmitter

When an EventEmitter object emits the event, all of the functions attached to that particular event are called synchronously.

All values returned by the called listeners are ignored and will be discarded.
