Thanks for this video.
import { of, map, Observable, switchMap, concatMap, exhaustMap, mergeMap, interval, take, delay } from 'rxjs';
of(1,2,3,4,5)
.pipe(
take(5),
mergeMap((val, index) => {
return of(6+'-'+val).pipe(delay(Math.floor(Math.random() * 10))) // Delay is culprit here changes behaviour
})).subscribe((resp) => console.log(resp));

[@mrunalgaikwad1786]

Thanks for this informative video. What will be the basic difference between forJoin and mergeMap? as per my understanding both can be used for executing the APIs parallely then what is the difference

[@mohsenmadi3590]

They are different! mergeMap has an outer and an inner(s) observables that emit values. forkJoin starts with two+ observables, waits till all finish streaming, then you can deal with their data in the subscribe region.

Tys bro....🔥🔥

[@medifittechs3218]

You are switching between context whatever you are doing. Firstly, explaination given from RxJs site is confusing. It is not all clear, you are saying same thing different way. Second, why are you showing routing in map function. Video should be to the point. Avoid saying sorry many times in video

[@mitesh5189]

10:10 same happed with me also i was confused

[@koyenadutta5747]

i did not understand

[@Hanneslueke]

Wow, you are speaking fast at the beginning

[@Johnp-f8i]
