Observable Operators vs Promises

What are the main differences between Observable operators and Promises in JavaScript?

Observable operators are lazy and can handle multiple values over time, while Promises are eager and resolve a single value.

Can you give me an example of when to use Observables instead of Promises?

Use Observables for handling streams of data, like user inputs or WebSocket messages, where multiple values are expected.

What are some common operators used with Observables?

Common operators include map, filter, merge, and switchMap, which help transform and manage data streams.

Are there any performance considerations when choosing between them?

Yes, Observables can be more efficient for handling multiple events, while Promises are simpler for single asynchronous tasks.
