Asynchronous JavaScript in ~10 Minutes - Callbacks, Promises, and Async/Await

The asynchronous nature of JavaScript to understanding the language. You'll find the use of callbacks, promises, and async/await in code that you write every day as a JavaScript developer. In this JavaScript tutorial, you'll learn about all three in about 10 minutes.

00:00 - Intro

I am not a native English speaker but ur accent is most suitable for me! Thank you for ur content <3.I wish u a healthy life.

[cameronthompson]

Promises are still a struggle for me. This has helped a ton. Thanks, James!

My teacher taught us Asynchronous JavaScript at the end of a class in 15 minutes and I got 0% of it. Thank you for this video

[everay]

I'm so glad to hear that asynch js is not only for me difficult to learn, because it's just not sinking in, yet. I'm grateful to learn from your videos, you can explain complex things simple.

[nikolaoskonstantinidis]

I understood these concepts better in your 10 min video than in many others 20+ min videos. Thank you.

[jazy]

you! This is such a beautifully simple explanation of the whole thing, starting from callbacks to async! Please keep on doing great job.

[oliviaseymour]

Hey! I watched a lot of videos, read a lot of articles, but only YOU explained these topics in a clear way! thank you!

[luxs]

What I love about your video is that you don't just explain the code based on the syntax, but you give conrete examples in which it can actually be used.
This also results in a very natural example for chaining promises (getting json from a response), which makes this super easy to grasp.
Thank you very much for making this!

Maybe you could take a look at using async await for concurrent callbacks as well?

[goodwish]

Best one on Async/Await I've seen so far. Excellent!

[ChikereEzeh]

Best tutorial on async I have come across. I am 'new' to JS and will jump straight into async/await.

[andredejesus]

Watched this as a refresher and it went better than I expected! Thank you for this

[soniablanche]

If you're using the fetch api I recommand checking the value of "response.ok" because code 404 (or whatever code error the pokemon api sends back) is not an error for the fetch api because the server successfully sent back a response.

[elaizaespanola]

You explain this so quickly and so easily. Thank you for your videos. Subscribed already!

[nemanjastankovic]

This is one of the best programming tutorials I've seen for quite some time. Awesome 🤓

[hedwigseidel]

One of the best explanations I have come across. Thanks a lot!

[joecolas]

thank you James for letting me understand better the JS Callbacks and Promises

[ammarhassan_]

Recently came across your channel via Twitter, Love ur videos., It took me 2 yrs to understand callbacks (give and back) but it was worth it, I can now know it is working and how to create HOF.

[NicoHeinrich]

Thank you, this video really helped! You did a great job at explaining everything 👍

[antonk]

This seems like a good syntax and concept introduction, what it lacks is actual explanation on how exactly these calls are executed, in what queue, order over time etc.

[alibaba]

I watched a couple of videos but only this one worked for me. Thank you for the amazing explanation.
