[@petetracy8757]

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!

[@WesDoyle]

Great to hear it!

[@prateeksharma3187]

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.

[@georgeflores5382]

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

[@vin2629]

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

[@DamonMedekMusic]

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.

[@The825178]

Very nice and clean explaned!

[@WesDoyle]

thanks Maja

[@nebojsadjordjevic8253]

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

[@ccaspanello]

Great tutorial! Not only did you explain how it works you go over pitfalls . . . the same pitfall I ran into. Thank you!

[@WesDoyle]

thanks Chris! glad to hear it

[@yofi2614]

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

[@chiranjeevichowdary5948]

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

[@taylorchristian2576]

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!

[@WesDoyle]

Thanks Taylor! Congratulations on your first year. All the best!

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.

[@erikalonso5782]

Dude, this. I was so confused by the arg passed to the then. function, like, how does it know it needs to fetch the reject or resolve data if the arg name has nothing to do with them?

[@jaffarsharieff8528]

Really a good explanation.

[@ondrejmarek9752]

Thank you so much for this tutorial.

[@TaylorRayHoward]

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

[@WesDoyle]

Thanks, Taylor. I hope we can catch up soon. Hope you're doing well

[@mocococo2877]

Thank you and greetings from Bulgaria. Please explain how can p3=1000 be a promise ? Thank you

[@danielgabay8816]

ty, you helped my understand better the promises

[@robertoenea8576]

Hey, nice video! Can you please tell me the name of the VSC theme? Thank you!

[@feliciabacon9923]

I was wondering about this too :)

[@morososaas3397]

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.

[@abdelsoumah4922]

Yes I was wondering where the data is coming from

[@viridianite]

Nice video! What program are using to emulate Vim inside VS Code?

[@Coderverse.Technology]

Great video

[@hemanthkotagiri8865]

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

[@WesDoyle]

Thanks Hemanth! All the best

I saw that Microsoft has added the static web app SWA builder on Azure. In your Udemy course, full stack, I think you connect the backend to the Vue front end using a product mapper to interact with an entity framework that stores its data in a Postgres relational database. Could you make a KZbin video on creating an MS SWA that connects to the API we're building in your course? Am I correct to assume that we can simply swap out the front end (Vue) for a front-end SWA running on Azure? And, are you able to show us how to do that in a 10 minute KZbin video (asking for a friend)?

[@hemanthkotagiri8865]

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!

[@WesDoyle]

I've been considering this for some time, thanks for the suggestion! I'll have to come up with a way to spark an interest in using Vim for those who haven't used it before - it can be a bit of a challenge at first, but it provides a fantastic boost in productivity once learned.

[@hemanthkotagiri8865]

@@WesDoyle really sweet! Looking forward for the video soon! I'm quite excited! You can call me your excited subscriber. 😉

[@sgamer1770]

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.

[@vishseenarain]

What vscode theme is that ?! 😲👌🏼

[@christianmarquez6365]

Awesome video!

[@WesDoyle]

Glad you enjoyed it

[@sudidav]

Thx Wes! I had a request, would you make a video about .Net core and flutter. Thanks in advance!

[@WesDoyle]

Nice idea Sudi David

[@sudidav]

@@WesDoyle Thanks again

[@arunavamukherjee7549]

Great video. When do we use setTimeOut()? Thank you in advance : )

[@kartiksaini5847]

subscribed good work

[@ScenicD]

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.

[@IvanRandomDude]

Looks like a Task in C#

[@WesDoyle]

They are related constructs! Check out TaskCompletionSource in C#

[@vijay_pachaiyappan]

hai bro

[@WesDoyle]

Hello!

[@prathamrajgor]

Your Theme is creating PROBELM. Cannot see brackets and other stuff clearly which makes the whole tutorial shit despite being good in terms of teaching.

[@SkullSkill912]

Mine says this: Promise {} [[Prototype]]: Promise [[PromiseState]]: "fulfilled" [[PromiseResult]]: undefined Is it still pending?
