EventEmitter vs Observable: What's the Difference?

Can you explain the difference between EventEmitter and Observable?

Sure! EventEmitter is a Node.js class that allows you to emit and listen for events, while Observable is part of the RxJS library and represents a stream of data that can be observed over time.

When should I use EventEmitter instead of Observable?

Use EventEmitter for simple event handling in Node.js applications. Opt for Observable when dealing with asynchronous data streams or when you need powerful operators for data manipulation.

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

Certainly! For EventEmitter, you can create an instance and use on to listen for events. For Observable, you can create one using new Observable() and subscribe to it to receive data.

What are the advantages of using Observable?

Observables provide a rich set of operators for transforming, filtering, and combining streams of data, making them very powerful for handling complex asynchronous scenarios.
