This is the sixth video I've watched on promises and the first one that explained just what they are so I understood it. Good Job!

I really like your tempo and the calm state at which you throw your knowledge on the screen . It makes easier to digest for the learners.

I make an effort to comment on every video that helps me out. Really concise, practical, easy to understand examples. Thanks so much!

Promises have been pretty difficult for me to learn. Its rarely taught in a clean organized way. However, I wrote a pretty complicated program using promises today and I'm glad I figured it out. Thank you a ton for explaining it. I'm really glad I can use it more as its very powerful.

This is the video every1 should watch for promises.I have seen many videos but no one explained like u.Thanks a lot bro

I loved the way you compared a promise in real life to the promise in javascript.! :D

IMHO for beginners in order to you understand Promises fully, you firstly gotta learn about callback functions to understand what resolve and reject methods come from. Secondly learn about node bcs. you gotta use terminal in order to see the result. At least it gave me some hints what is going here for the first time.

Great video Wes! I love how you explain things. I just finished my first year as a backend developer and all of your videos have helped me along the way. Thanks so much and keep up the great work!

[nebojsadjordjevic]

great video mate thank you so much i was struggling with later part of promises when we introduce then, but now i understand it fully. Thank you

[danielgabay]

ty, you helped my understand better the promises

[TaylorRayHoward]

Digging all the new content. You're killing it.

[morososaas]

I think that what confuses many people me included is that it is rarely told when chaining promises that behind the scenes the .then(callback) takes automatically the data from the successfull promise as an argument.

Thank you and greetings from Bulgaria.

Thank you

[hemanthkotagiri]

So you took care of my advice! Thank you so much for that! This is a cool video!

I'm very confused about the require thing, first time I've heard about it was in this video and now I'm trying to figure out how to do that.
Otherwise, great video.

PS: I've been studying JS for about 2 months.

Hey, thanks for the tutorial, can you please explain what the data in the parenthesis stands for? 09:09

[sgamer]

i'm a bit confused by the use of arrow functions buried deep within the promise multiple times. perhaps a video on that you could make please. the first 8 minutes before that i extremely enjoyed.

[hemanthkotagiri]

Can you also make a video on learning Vim editor, please? I've seen you in that live stream using it like a pro. It would be great to see a video on that from you because I feel you are explaining things in the most simplistic and best way to understand. Looking forward to that video!
