mergeMap in Rxjs | concatMap in Rxjs | mergeMap & concatMap in Angular
Показать описание
MergeMap is best used when you wish to flatten an inner observable but want to manually control the number of inner subscriptions. In merge map order of execution is not maintained and if want the order of execution to be maintained then you can user concatMap.
MergeMap can be used to make a parallel call HTTP call from the application and catching error in the mergeMap is also pretty simple.
