The Story of Asynchronous JavaScript

This is the story of callbacks, promises, and Async/await in JavaScript.

Really pushing the bar for programming content man. Thank you for these efforts. So hyped for the next generation of engineers who get to grow up with stuff like this 🙏

The phone number vs. buzzer analogy is the best explanation I’ve ever seen on this topic

[KevinVandyTech]

I've used all of these patterns at some point in the past, but never fully understood the pros and cons of each pattern. Your videos are always the most clear explanations. Thank you

Wow that buzzer/phone example was a stellar analogy for promise/callback

The first time I witnessed AJAX in action was on the Microsoft Developer Network web site circa 2000. It was being used to dynamically load expanded nodes in the table of contents. I remember calling over other devs to show them and we were all trying to wrap our heads around this sorcery. What a low key way to introduce such a revolutionary thing.

I love the historical context presented in such a succinct way. Will definitely point all junior devs I come by to these videos to get their bearings on how we got here.

[MalikMehsi]

That's the best video on promises I have seen so far

[fyriss_]

these videos are one of the best on the whole platform, can't wait for more. It's especially great for young devs, who don't know context of some things in the past that well.

This is one of the cases where C# was revolutionary. C# brought the async/await pattern (in 2012) almost 5 years before JavaScript implemented it (in 2017).

Holy crap, this was the clearest, most concise explanation I've found for this topic. 10/10.

[sjadev]

These “The Story of” videos are pure gold.

🟡Wonderful hindsight and clear vision of technological advances.

[adityakachroo]

This is the best explanation of async/await. I always struggled in understanding it fully. Thanks for this amazing informative video

[warkentien]

The simplicity and depth of these tutorials are second to none.
Congratulations on the channel!

Haven't seriously done web dev in 13 years and let me tell you, it's a completely different ball game now. I barely recognize JavaScript along with my outdated HTML and CSS. I don't miss it though, it was a horrible mess before and Internet Explorer 6 is no longer anyone's worry. Good job to everyone involved in pushing the technology further and thank you for this brief summary of something big that I missed.

[pictzone]

This channel will blow up. Glad I found you early. Exceptional information and love your point of view on this kind of stuff.

[smoothbeak]

Beautiful explanation, probably the most clear and extensively explained example on this I have seen

I get so confused learning JS man. Async is crazy for me rn… When I started digging in to async await a couple weeks ago I somehow found myself putting callbacks in my .then() functions. The other day I was writing Promise constructors inside async functions then trying to await them 😭😭

Learning JS I’ve found it’s less about syntax and more about concept. Knowing what you need and where. Videos like this help me organize these concepts so no matter the syntax I can always keep myself oriented in the code.

For example, my end goal while learning async Js is to be able to refactor code from callbacks to async/await. Not through memorized syntax, but because I understand that success, failure callbacks turn in to resolve(), reject() and that the callback functions are turned to thenables. Same with going from Promise constructors to async/await.

Sorry for long comment I’m an aspiring dev with no one to talk to about this stuff. Also if I said anything wrong please correct me. I need knowledge lol.

I'm pretty confident with async Javascript but this was a great history and refresher. Well explained Tyler!

More of these docs! As a web dev cutting my teeth in the modern era, where most things are abstracted away from you, context of where these technologies came from is invaluable.
