That's what is called under the hood !!!! I searched a lot of TH-cam videos to understand promises but they explain only syntax. This video completely gives an AHA moment after understanding promises. Thanks Instructor!!!!
Finally, FINALLY I UNDERSTOOD PROMISES. This is the best explanation ever! Well detailed, from scratch, without assuming anything, without the bragging of other youtubers. This is education! Take it from me, a college professor and web developer. You are GREAT, Samantha.
Incredible watching this to notice how much essential information is missing from most Promise tutorials ive come across. Annoyed it took me a few videos to remember to check for a Codesmith lecture, have to be some of the best going. Thank you for sharing!
Wow, amazing content! Does Codesmith cover Observables and that whole ecosystem so to speak (i.e. Subjects, Observers, BehaviorSubject, etc)? I'd love to learn about this topic from Codesmith since things are explained very well and thoroughly.
What if the callstack is empty and XHR/API request takes longer time to execute before invoking the onfulfillment function carrying the data returned from XHR/API call and placing it in micro task queue? which means micro task queue is also empty and there is a callback function waiting to get executed in the callback queue. What happens here? Does the callback function gets called?
I dont really understand the .then part, while this makes the code more predictable, can anyone share any post or something that backs up whats said in this vid that .then pushes callback functions into hidden unFullfillment array?
:/ to havy for me :/ this presentation is for people who knows already very well JS, not for medium_beginners :/I hope I will come back to it one day !
if you first watch a video about execution context and call stack, you will understand this one very well. This series not for absolute beginners, but for beginners who want to understand how things work in javascript.

agree with you 100%
Its a best lecture that i have ever seen on this complex topic

Thank you and we are so happy to hear you were able to figure out Promises!
This was the most helpful lecture on async JS I've watched. Thanks Samantha!
It's just a brilliant explanation that helped me a lot! Thank you, Samantha!
Great timing as i was finding it hard to understand callbacks and promises. Looking forward to see the async\await video.
One of the best videos explaining how async code & promises actually work under the hood.
Thank you!
Glad it helped 🙏
These under-the-hood videos are very helpful, thank you!
On par with Will. Great Explanation !
Sam's amazing - glad you enjoyed it
