RxJS sequence equivalent to promise.then()?

Question

I used to develop a lot with promise and now I am moving to RxJS. The doc of RxJS doesn\'t provide a very clear example on how to move from promise chain to observer sequenc

Answer 1

If I understood correctly, you mean consuming the values, in which case you use sbuscribe i.e.

const arrObservable = from([1,2,3,4,5,6,7,8]);
arrObservable.subscribe(number => console.log(num) );

Additionally, you can just turn the observable to a promise using toPromise() as shown:

arrObservable.toPromise().then()
