Complete Guide to JS Async & Await ES2017/ES8

[@Lioncodes]

Honestly Colt, this is one of the best tutorials regarding programming on KZbin. You've taken a topic that seems convoluted and "scary" for beginners and broke it down into easy to understand bits. We understand that KZbin isn't always the best use of your time regarding ROI, but we greatly appreciate it.

[@ColtSteeleCode]

Thanks for taking the time to type it up! You're right that KZbin is definitely not a big earner for me (I think I've made $200 in my first year) but I do actually enjoy making these videos. Recording massive 20-40 hour courses can get tedious and a little boring at times. KZbin videos are always more challenging and fun to create. Plus eventually I'm sure KZbin will lead new students to my courses and upcoming projects. Glad you liked the video!

Nobody explains things with such an ease and engagement at all! The best!!

[@TA_Solberg]

Thank you for this! I love that your youtube content is sort of complimentary to your Udemy courses and I really hope you can make more of these. Btw, it wouldn't bother me if you start advertising as long as it helps you, seeing how much you help us out.

[@vasilacheandrei4072]

Hello Colt! I want to thank you for everything. A year ago I bought your web development udemy course, and I learned from it how to make a lot of cool stuff. After finishing that course I made 10 projects and a Portfolio, beeing hired by a local company on age of 18 years. You are the best teacher I ever seen, keep it up! I hope you the best! ❤ ❤

[@ColtSteeleCode]

Hi Vasilache, thank you for the great comment. It's amazing to hear from students, especially ones who get jobs! At 18! That's incredible. I hope your job is going well, and you're continuing to learn new things :)

[@dextermorgan7764]

Hello brother, I am almost finished with the course 83%, I have no idea what projects to create, are your projects on github? I need some ideas for my own projects.

[@vasilacheandrei4072]

Hello! Here is the link with my personal projects : github.com/gfx96?tab=repositories Becouse the code was written when I started codding, it can be a little bit messy, sorry for that. I recomand you to just see the idea, and think the problem by yourself, not to copy the whole code from project. Hope I helped you! Good luck in the future, and if in the process you think you are a weak programmer, just trust in yourself programming it's about self confidence and patience.

[@olaboyeolanrewaju134]

@@vasilacheandrei4072 I have also built projects after finishing the Web developer bootcamp. Colt is the best person I ever learned from this video demystified promises as well as async/await for me

[@manoranjandash5424]

You are not just a trainer, but a emotion to programming

[@lunchfoot]

As usual, you have the ability to provide crystal clear understanding of whatever subject matter you are teaching. The best!

Have undertood async functions by just watching this 16min video. Thank you!

[@bloxzyo]

This is the best async await youtube video... also this works like a summary to what you taught on async await in the js bootcamp course.... your courses are really good.... Im enrolled in most of em and will be following the remaining courses after I complete the ones i am already enrolled in.....

[@envaya9838]

Stillb y far the best tutor out there and pretty much the only one where I understood everything as someone coming from a completely different field. Please make a full video about js callbacks and promises!

[@FalkorX]

Very good explanation, as always, thanks! I personally like to throw array destructuring assignment into the mix, goes very well with parallel async/await code: let [p1, p2, p3] = await Promise.all([ $.getJSON(`${baseURL}/1/`), $.getJSON(`${baseURL}/2/`), $.getJSON(`${baseURL}/3/`) ]); console.log(`The first pokemon is ${p1.name}`); console.log(`The second pokemon is ${p2.name}`); console.log(`The third pokemon is ${p3.name}`);

[@muhammedismail8299]

So happy that you're uploading regularly

[@ColtSteeleCode]

Hi Muhammed, don't be sad if things slow down a little bit in the next week or two as I pack up my studio and move. I'll do my best to keep putting out frequent videos, but it's not easy :)

[@sidarjunful]

The refactoring part was awesome to know.

[@udev6707]

Best explanation ever, this is what I was finding from last few hours, Thank You!!!❤❤❤

[@luisalbertogarciaibarra9852]

Awesome content. I wouldn't mind you advertising or even asking for donations. You definitely deserve it.

[@MEVEN5]

Best explanation of async/await on youtube!

[@hdjfgt]

Thanks Colt! I bought your first web course on a whim half a year ago and after that I was hooked. I'm probably going to get all your courses sooner or later. I don't feel comfortable looking for jobs yet but thought it might be cool to know that after taking your bitcoin course and about half of your python I was able to create the world's shittiest bitcoin block explorer, then the world's worst bitcoin address generator (you can spend outputs from it too) and finally a horribly slow bitcoin miner which is completely pointless of course but I managed to mine a block in a testnet. So thank you, I'm a huge fan of your content and your style of teaching

[@jinwookkim8511]

Colt, you are a genius

[@vitaliyd23]

[@ColtSteeleCode]

Thanks Vitaly!

[@vladimirkim7830]

Best instructor on the web!

[@piotrrytel6208]

Colt explains difficult concepts in the way that's understandable. I would love to see the video about algorithms or solving problems in JS (smth. like factorials, string reverse... ) and other topics that you can encounter on a technical interview. Some of you are not aware but Colt has really good Udemy training for those who want to become a webdev. Good job on the video Colt! Keep up with the content production!

[@yadhukrishna206]

As usual Colt explains it perfectly. I'm a student from your udemy courses. Excellent work. Thank you.

[@GarmrZero13]

Hi Colt, I'm really enjoying the content of your channel, especially when you delve into JavaScript. I was wondering though if you would consider word-wrapping your code so it isn't cut off?

[@ColtSteeleCode]

Thanks for the message! I turned off word wrap for a project I was working on that had a ton of super long strings. I didn't want them taking up so much screen real estate, but then I completely forgot to turn it back on for my videos. Thanks for letting me know :)

[@arber.shabani]

Amazing video Colt!! Thank you!! :D Could you make a video for best practices in error handling with async/await?

[@olaboyeolanrewaju134]

He already did in this video, using try and catch keyword you can handle errors in an async function check the video between 8mins:40seconds and 9mins:30seconds

[@rohanshenoy8353]

Love your content as usual. I would like to suggest something. Since you have already covered JavaScript in you web developer boot camp 2016 as I recall. It didn't have contents of es6, es7, es8 and even some latest things like webpack and Babel. So maybe you can make a series or udemy course on that, with multiple projects (if on udemy as KZbin it'll be difficult for you) . Thank you :)

[@aidenstill7179]

is there a possibility that you will create a machine learning course with python?

[@ColtSteeleCode]

To be completely honest...I would have to work with someone to make a course on machine learning. I don't feel comfortable enough with the material to go and teach it to students. I play around with a lot of machine learning tools on my own for fun, but it's not something I've worked on in a professional capacity. I would need to team up with an expert to help create the slides/content, which is something I have definitely thought about doing.

Colt, thank you! Do you think Jquery has a (good) future?

[@bensonmkurian2071]

But why/how does await work in parallel execution? Since the promises are already created in advance ...? But still, when calling await on each promise, doesn't the program pauses the execution until the current promise is resolved.....??

[@siddhantjain2402]

I love your content man!

[@RobertWildling]

Thank you for this insightful tutorial! One question, though: Is the try-catch-principle valid for the Promise.all(), too, or is there a similar more compact approach available? ```javascript // try-catch within await Promise.all([...]) let prokemon = await Promise.all([ try { $.getJson(...) } catch (e) { console.log(e) }, try {} catch(){}, try {} catch(){} ]); ```
