Promises vs Observables - Angular (Tutorial #30)

Promises and Observables are 2 ways through which we can perform asynchronous operation in angular. In this tutorial , I will give you in depth comparison between both and we will learn how observables is preferred over promises
Promises are built-in in javascript whereas Observables comes from RXJS library which use to perform asynchronous operation.

    To be hones I have watched multiple videos on the difference between observable and promises, everyone says the same but no one demonstrated that. I feel myself lucky coming through this video. you have explained it really well. Can you please create a playlist over seperate RxJs? Thankyou so much you are out there. Please keep on this. we need the people like you🙂

Your way of explanation is superb, anyone can understand easily by watching your tutorials. Can you please make a video on angular version upgrade. I don't know anyone that who can explain that IN detail. Suppose we want to update our angular app from 10 to 11 or 11 to higher version what are steps we need to follow , what the mistakes we will do usually and which files we should handle with care....
