[@prasadnarayana7257]

Wow
I'm speach less
Thanks from my bottom of heart ❤️

[@robinr2336]

@9:03 why does the observer.next() method do in the AsyncStream function? Thanks.

[@monishussain2839]

It will keep on emitting the data..from asynchronous function

[@robinr2336]

@@monishussain2839 thanks

[@himanshuupreti619]

Watching interviews question. In your channel

[@robinr2336]

@8:20 why is "create" function striked out in the code?

[@piyushp9255]

It is deprecated

[@EeshaKPopDanceCovers]

Sir..here 'res' is the observer..right??

[@questpondvideos]

The function which goes in Subscribe function.

[@aneeshrajr2418]

Hi sir - Could you pls do webapi questions also?

[@questpondvideos]

WebAPI questions we have covered in ASP.NET MVC Core QnA subscription :- www.questpond.com/aspnet-mvc-core-interview-questions-and-answers/cid73

[@gopalgupta7402]

Please explain ngrx

[@questpondvideos]

As this was very focussed on rxJs , NgRx we can take as separate video.

[@joecok]

Pls start with observer pattern also, that will help a lot

[@vasudevchouhan7551]

I would like to point out answer for question3 is not accurate. Observable not only produces async data it also produces sync data.

[@questpondvideos]

If you can handle Async , Sync is implicit

[@SumitGupta-wr3jf]

Pao kaha hai sir aapke

[@anuragranjan6739]

I missed questions on subject .

[@ricko13]

Companies be like: why is the Rxjs logo a fish?

[@sureshmani46]

Thank you sir

[@sammyyou7712]

Awesome
