What are the differences between EventEmitter and Observable in Node.js?

EventEmitter is a Node.js built-in class for handling events, while Observable is part of the RxJS library for reactive programming.

Can you give me an example of how to use EventEmitter?

Sure! Here's a simple example:

const EventEmitter = require('events');
const myEmitter = new EventEmitter();

myEmitter.on('event', () => {
  console.log('An event occurred!');
});

myEmitter.emit('event');

How does Observable differ in terms of handling asynchronous data?

Observables can handle multiple values over time and provide operators for transforming data streams, unlike EventEmitter.

Which one should I use for my project?

It depends on your needs. Use EventEmitter for simple event handling and Observable for more complex asynchronous data flows.
