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.

I love the way you teach, with flow. I can understand it clearly.

[@furquansaifi4294]

this is undoubtedly the best explanation I have encountered anywhere till now in my 5 years of working with Angular.

[@ashwanikumar183]

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🙂
