[@Explorewithmishu]

at start I didn't understand anyone. but once you started giving examples ,I was able to. Thanks

[@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.

[@siddhivinayaka3141]

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));
