What are the differences between Observables and Promises in JavaScript?
Promises are single-valued and represent a single asynchronous operation, while Observables can emit multiple values over time.
Can you give me an example of when to use each?
Use Promises for a single event like fetching data, and Observables for streams of data like user inputs or WebSocket messages.
Are Observables more powerful than Promises?
In many cases, yes! Observables offer more flexibility with operators for handling multiple values, cancellation, and more.
How do I convert a Promise to an Observable?
You can use the from
operator from RxJS to convert a Promise into an Observable.
