Why choose ngRx over shared angular services? 1 point
-
How are fork join and merge map different? 1 point
-
How do we wrap html elements in our custom component? 2 points
Ex:
This is not a paragraph element
- How will you handle an error produced by RxJS operator's inner observables without failing any other observables that are yet to emit values to its subscriber, so that all the inner observables including errored ones can be piped to another RxJS operator such as fork join, concatMap etc to be handled smoothly for further operations?
Easiest thing would be to generate a pseudo code.
With above question solve this problem:
[Observables....] -> Emit values simultaneously from the array of observables at once (perform a task when an observable finishes) -> toArray -> [emitted values...] -> process each emitted value one by one -> toArray
