Asynchronous JavaScript Tutorial #1 - What is Async JavaScript?

Hey gang, in this JavaScript tutorial series we'll dive into async js - from the very beginning. Rather than just start using fetch, async & await from the start, we'll take a closer look at async code & how it all works under the hood.

Please, never lose your teaching style. You rock among all of these teachers on youtube.
I really appreciate that you always try to explain every single topic as thoroughly/carefully as it's possible. Good job!

The best JS Instructor on this planet, I suggested your channel to all my juniors

This is why some people will make heaven. Love you plenty, I took your React Context & Hooks, it really makes me feel comfortable using it in my project. I happened to be in class where someone was explaining React Context & Hooks, I was able to explain it to my classmates even better than the tutor in a simplified form using your method. I can boldly say this you and Brads Traversy, the very reason I am still coding and better at what I am doing. Thanks a million.

Async await is heaven. Haven't written any callback hell in 3 years and it feels great. Best part is that you can await on new promises, so you can easily utilize legacy code with callback hell by just wrapping it into a promise and waiting on it.

Just have to say is you're really good at breaking down complicated topics. You're awesome

[paristonhill]

Don't waste your time searching for other "asynchronous" tutorials, this is by far the best series trust me!

[BlueyMcPhluey]

yay, thankyou so much for this series!

I was just thinking to myself a few days ago that I wish I understood this better and that you're the best teacher for web dev

This is the first time I have ever understood what Asynchronous Javascript is. So simple, so straight-forward. Why do other video speakers over complicate it?

[matthewblasco]

MY GOSH!! I've come from tens of videos what why how and stuff about asynchronous Javascript, why use promise, and why are they using setTimeout for their examples. and Alas! This video of yours clarified what the heck is asynchronous programming, at the same time, why it's needed, and the use of setTimeout!! It was to emulate what the async JS does basically, then. Ahhh!!!

Thank you sensei!

Just this Friday past I refactored a few functions to replace callback hell with Promises and async/await. Including a few other optimizations, I brought code down from about 350 lines to around 180 👏.

Yesterday I have completed Async JavaScript module from your Udemy course.
It was awesome!

[SunilSkanda]

One tutorial after another. You're on fire 🔥

[himalayagupta]

isn`t this the best explanation of asynchronous js on internet ?? Thank you so much 😊😊. You got yourself a subscriber

[jykw]

I mean dude... why are you so awesome? I'm joining a new company in April that's using JS, TS, node, react as the main stack. I come from strong Python background and busy taking your courses. You're just KING.

[michaelhorvilleur]

I have watched countless videos on this subject, and I didn't understand it until now! Keep the videos coming please!!!!

[adiathasan]

Honestly, I'm becoming a react ninja because of this lovely channel. All love from Bangladesh <3

[nodehash]

There are quite a few top-level techTubers out there right now. You are - IMHO - at the very top of the pile. Your method of explaining things beats even the mighty Traversy, again IMHO. And that is saying something lol :)

[dunyan]

This shit is way better than most CS lectures. My dog watches your videos and it became a wolf, thank you!

[enai]

We need to petition Youtube to add a Heart bottom because I'm absolutely Lov'in this course.
Thank you Master Ninja, I learned a lot today :D
