What is promises and observable? Differencd

Question

Accepted Answer

Promises and Observables are used for handling asynchronous operations in Angular. Promises are used for a single value while Observables are used for multiple values over time.

Promises are used for handling a single asynchronous operation and can only be resolved once.
Observables are used for handling multiple asynchronous operations and can emit multiple values over time.
Promises use .then() to handle the resolved value while Observables use .subscribe() to listen for emitted values.
Promises are eager, meaning they start immediately upon creation, while Observables are lazy, meaning they only start when subscribed to.
Observables offer more powerful operators like map, filter, and reduce for data transformation compared to Promises.
