Can you explain the benefits of using RxJS observables on promises?

Do you mean VS?

Promises are single value and always async. They are eager and stateful with only a few transformation options like then and catch.

Observables can have multiple values, are sync OR async, generally stateless, and have many transformation options out of the box via RxJS.
