Glad he returned the promise that we've long awaited

You’re the only guy that I slow the speed down instead of skipping or speeding it up 🙂. Love the emoticons in the code, how do you do that?

"When you're start making promises that's when you're more likely to screw things up" That's also how it works in real life. Noted.

You Promised, and we awaited. ...Sorry for bad joke

You deserve so many more views, favorite channel about development on youtube

Promise Statements and Async Await are the favorite things I've recently learned about in JavaScript. This lecture was/is right at the borders of what I understand, and was challenging in a good way. I appreciate the visuals. I really appreciate the additional lecture resources you mentioned. I will study them and loop back to this periodically until I'm clear on what was presented.

I was debugging something for an hour and decided it's finally time to fully understand the async / await functionality, turns out the concurrent map execution was the issue lol. Thank you for the quality content (from 4 years ago), you are helping me a lot and everyone else in the community.

Being new as a developer with just over a year coding and picking up JS as my main language a couple of months back, this video explains so many of the issues I have encountered coming from a synchronous language (Java and Python) to async in JS and TS. This channel does a great job of explaining essential concepts to newcomers like me. I'm glad I found the channel. Thanks!

It blown my mind. I need to study a lot yet. Great video, thanks!

This video is from Oct 11, 2018. It is still one of the best explanation I have ever seen. It is just so clear. And that recommended video about the NodeJS event loop is a must-watch for JavaScript developers. I am an Android Developer and I saw that video. So if you are JS Dev and you did not, you might be a bit late. No worries there is still time. :P

I have learned so much in a short period from your channel ... you deserve tons of credit

Found your video of right good code not 💩 in my feed, loved you style of explanation and the way you provide the video editing is exceptional 🤩 one of the channels I'll definitely share and follow!

My mind just was blown away, amazing tutorial, as always.

It's good that you explain the background of async/await! I consider those keywords both a blessing and a curse. In my experience, people new to JavaScript use it without knowing what's going on in the background. This often leads to bad results which they don't know how to resolve. When you know how promises work, you can actually appreciate what async/await is abstracting away for you.

This was one of the videos that I didn't want to skip any second!! GREAT JOB ! Much Appreciated!

The best video I've watched so far for await / async. I covers all the aspect in such small duration. Loved the emoji too :D

Typo at 8:00, screen on the right, line number 67, it should be a=v. Great tutorial! 😀

Holy shit! I had no idea about the for await... loop! That's amazing, thank you!

This was very helpful. I like how rapidly you gave instruction, yet made it very clear.

LOVE this... You've helped me so much understanding this concept.

I love this channel and maintain a pro subscription over on their site and have found it to be more than worth the price of subscription, free access to current and upcoming courses is amazing and I love how a lot of the pro videos are a direct and more in-depth look at an earlier free video with an emphasis on real world use case scenarios. This video is excellent and really helped me to further understand how and more importantly when and when not to use async await in my code. Thanks again man and keep producing incredible content!

Hats off to you, you legend. It's mad that you can symmarize all of these concepts into just 12 minutes while making more sense then all the other videos out there that take 3-4 times longer.

Your way of explaining things is just amazing! Thanks 😊👍

bravo - the best 12 minute clear and simple explanation of promise, async/await I have seen to date...

It’s insane how quickly JS is developing new features. So excited to see what happens next or if we can get an ES based typing system. Thanks for the vid!

Man you definitely deserve much of the credit for the success of my future StartUp^^ Please don't stop, your videos are making the world a better place, thank you

I ll feel so grateful finding your channel. As soon as I start making money , gonna buy those awesome courses

The clearest explanation of async/await that I've encountered. Well done!

I'm a backend dev and I just wanted to say this was a brilliant to-the-point video. I had to watch it twice but very invaluable. Subbed.

Great video! But I wondered if there might be a mistake around 8:00 on the right side. Shouldn't it be 'a = v' instead of 'v = a' if the code should be doing the same? Thanks.

Great content! I love quality and how well thought all of your videos!

You just showed me how much more ground I need to cover in JavaScript. Gets me excited to see I'm not even 10% done. Keep it up 👍🏿

This video cleared a lot of things up for me, thank you!

Incredible video. I avoided async and await because I didn't know what I was doing but now I think I get it

Another great tutorial from Mr. Delaney! Bravo!

Nice explanation , learned a lot about async and await. Thanks for you frequent videos on practical topics .

Great video! Great explanation, great quality, hoping for that free shirt!!

no jokes? i feel REJECTed didn't know about the for loop stuff, cool! about the try/catch: should i wrap all the awaits in one or use a separate try/catch for each await to treat better different errors? great video as always!

i swear to god for every two minutes i spent watching this video, i had to pause and go read about 2 hours worth of material. Totally worth it tho, i love this fast paced style of teaching.

Great explanation, specially when you started it from event loop. Loved the video as well as "Fire.......base...". Thanks

New subscriber here. the content quality of video are Amazing. i need this in my api thanks

Ok newbie on JS and programming here. Didn't understand most of it, but is fun watching intermediate/advanced content like this and wonder if in my future I'll be able to comprehend and do all of this by myself.

the Jake Archibald talk is fantastic! your tutorial too! thanks

So far the BEST EXPLANATION I've seen of it with practical usage and short

I'm just gonna let this video _sync_ in now

This is top tier stuff. I've been watching Fireship for like 2 years, but it's only now that I'm finding myself forced to actually learn webdev for good. These old videos are still incredibly sharp, I'm really impressed.

Each an individual day is a learning from you guys, you guys deserved much better. Await for the T-Shirt

Concise, fast a great explanation. Kudos to you sir

I await for your next video :)

after studying and learning javascript, getting certificates from 4 different online completed courses, I watch this video, get depressed and rip up all my certificates and start all over again. so depressing :( because i now feel like I didnt learn shit from those courses and have to start all over again from scratch. ooh well, back to html and css and eventually javascript yet again :(

Before I watched a lot of your videos I was in the first part of the Dunning-Kruger effect, but after watching a ton of your videos I now realize how much I don't yet know.

Discovered your channel very late. Thanks for such a clear explanation.

"The Async Await Episode I Promised" ...and that's how you make a video title.

Got one question that's been bugging me and I can't wrap my head around it. The code on the right - line 67, shouldn't it be inverted? meaning a = v? Because otherwise you would be assigning *v* to an undefined value, and what you should be aiming for is to store the value you have in *v* into *a*, that's the propose of *a*, right? (Pleas someone tell me what I'm missing, thank you)

Instructive, as usual! Thank you for clarifying some things about the promises.

Always like your video's, really educational. But I always have to watch on 0.75x speed else it goes to fast to understand.

and i set the speed setting to 0.75 for this

Your quality of videos is absolutely incredible Sir.

This video is the best Async/Await video on UKposts! Keep it up!

I think you broke my brain.

Holy sh*t i need to let this "sync" in so that i can "await" for better time to "express" myself and "promise" to come back....

I am binging your channel. It's been 2 weeks and am already loving web dev 😀

Top tier stuff. I didn't fully understand the looping concurrently / await individually until now.

i thought it was a 12 min video but i have to watch a 35 min video :(

Async/Await is a double-edged sword. It's a great addition to Javascript but it's also massively misused. I'm trying not to sound "elitist" here, but the complexity of promises and RxJS set a barrier for entry. People needed to understand how to write reactive code, work with asynchronous functions, etc. Now Async/Await has become the hammer for every timing bug that looks like a nail. I've seen the async and await keywords peppered through code in the hope it will magically fix a timing issue, mountains of code needlessly synchronised to the point it's stuttering to a halt on every page load. Hopefully people will take your "trolling" on board and gain an understanding of how it works. Really happy to see the pitfalls covered as well as the benefits.

This video has helped super-refine my understanding of asynchronous programming in general

I admire how you explain why async await even exists in the first place and that you should use it in a certain way to achieve maximum efficiency. Keep it up ur the best, OG subscriber :)

Don't leave a comment! It ruins my chances for a free T-shirt! (Great video!)

So fast u made it so complicated you get me lost more than i was hhhh

Nice, thanks so much. Jake Archibald really made it clear for me whats going on. Your stuff is always great and i always get something from it even if i think i know already.

This has been madly helpful. I wish I knew this 2 years ago!

watchVideo() .then(comment()) .then(winTshirt());

I liked it but it was too fast to digest. Could you please consider making videos less faster. Truly appreciate the value of the info. Thank you

Never disappointed with your videos Jeff!

You share best tech knowledge that too wrapped in smallest amount of time... Kudos... Loving ur stuff 😊

Serious question. Does anyone really like this speed? He is certainly very knowledgeable but I doubt if anyone can really understand him.

async winnerTShirt() { await('ME'); }

Wow. Such a lovely explanation. Great work

Always learn new stuff when I come here. Good content

The explanation is not very succinct. You could have explained a bit slower

Whoa whoa, slow down a little man. Great content but you are going way too fast. I know it definitely takes more effort and may not be worth it, but if you type out the code instead of coping and pasting the slowed pacing will make it much easier for your audience to grasp the concepts.

Really indeed very cool!!! Feels like an hour of tutorial. Thanks

Amazing channel mate, nice emojis, nice content, everything just nice

you talk so fast. i cant watch whole things clearly

Great job, however, this was very fast. It`s so much info in 12 minutes. I was pausing and rewinding hundreds of times.

Great video, very well explained like all your videos. I wish I saw this about 2 years earlier. Interesting would be how to cancel a promise, let´s say that user opens a page that starts an request, but he quickly navigates away, this request is still ongoing and after the request is finished it callbacks a code in a component that is no longer on screen (happened to me few times when working with react and redux then I got console errors), I know that this is not natively supported but there must be a way to achieve this and there are lot of discussions about different ways.

awesome job. love your vids, keep the coming!

that's way too fast. I got discourage after 2 minutes

What a video, brother! I've read about it and watched quite a few videos with examples and it was still not clear. They all show you a promise converted to Async/Await...all of them failed to provide the context with the event loop in the manner you did. Best explanation hands down. Thanks for the great content. I just subscribed. P.s.: Yes...3 years after the last comment... :)

Thank you so much. Your tutorials are great 🥳. Greetings from Chile

Wow! Just wow. Have no words to explain. You were really clear..... Thanks a lot.

Very informative and well explained, thank you bro

I had spent lot of hours to read so many articles about async await & promises but this guy clear my concept in just 10min

Thanks alot, I was struggling with Ajax call , this is exactly what I needed. I found your channel with your video on good js code , and damn I thought I knew a lot about js but finally not :D , thank you sir !

Awesome content, i'll check the Jake's Talk and the Demos with Angular. Btw, that font looks awesome! what is the name of it?

Not sure if the smoothie was so sweet or async/await :) Great video as always!

Lovely info! Well done and thanks for the good content!

Oh my god thank you! I will be watching this video every single time I need to write asynchronous javascript for the foreseeable future. I have been making a couple of these mistakes you pointed out. This video deserves 20 billion views.

Such a great video. Thanks for the solid content

The video you promised that we long awaited for.
