Thanks for covering all the details or concepts which most of them don't explain

A minor suggestion you can minimize the font size it is little big and only a small portion of code is visible.

The way you explained it helped me understand this topic better. Thank you!

Great video but I got confused on the chaining. I did check out other videos, they all show the chaining syntax but don't really explain how .then on a promise object actually returns a promise object and hence you can call another .then on the new promise object. You did hint at it during the video. So my question is when you don't do a return or return a value/function/object in a .then, how does that create a promise?

[siddhant]

Ok so the only point of chaining a promise comes into picture is when you want to return a promise inside a '.then'. And What do you mean by making an async call to get the user data? Am I correct ? I understand the concept of promises but this promise chaining is very hard to get my head around.

Dear Tapas.
I find your video very informative and easy way to learn JavaScript. However, I would like to 1-0-1 conversation with you. Please share your mail id with me.
Thanks.
