[@WebTechTalk]

Thank you so much!!

[@sharathmadamraju4086]

Very great explaination, but I think you need to change the timestamp name at 6:20 from "PROMISES ARE ALWAYS SYNCHRONOUS" to "PROMISES ARE ALWAYS ASYNCHRONOUS". As you mentioned that Promises are only ASYNCHRONOUS in the video tutorial, please change the Timestamp name.

[@WebTechTalk]

Thank you very much for pointing that. I have corrected that now. 😀

[@matthewkk5087]

[@senthamarai_kannan.]

promise = asynchronous
observable = synchronous (we can make it asynchronous)

[@WebTechTalk]

Yes. That's right
