ES6 came with many new features, but one of the best features was the official introduction of Promises. Promises allow you to write clean non-callback-centric code without ever having to worry about callback hell. Even if you never write your own promise, knowing how they work is incredibly important, since many newer parts of the JavaScript API use promises instead of callbacks. Checkout the full video to learn how to define and use promises.

If you enjoy promises make sure to checkout Async/Await.

The best and straightforward explanation ever!
thank you
You're the best
From arrow syntax now here to make promises
There is something misleading in the Promise.race scenario. The first promise isn't the first to complete because it is so simple, it is the first to complete because all the code executing is synchronous, therefore the first to complete is the first in the Promise.race call. No matter how complicated the first promise call is, it would always be first. I have seen many developers mistake the Promise object for creating async behaviour, when in reality a Promise only behaves asynchronous if the code inside the promise is doing something async.
u look like jorden
OMG you really simplified it
Clear, concise, and paced very well. thank you!
Hi Sir, can you please make a promise with for loops ?
Excellent explanation bro. Big help. Keep it up
Me: How the F do I use an API?
WebDevSimplified: Take my hand.
Awesome video, totally saved me
Hi Kyle! First of all, I'm new to the channel and I very much like the way and the speed at which you explain concepts in your videos. I have one question regarding Promise.all([promiseOne, promiseTwo…]) syntax. Does it always resolve in the same order you passed promises in or does it depend on something else?
This dude really knows how to teach
thanks bro, nice and smoth video
Great Job! Thanks!
thanks King👑
your keyboard sounds like trash.
Is this basically a more complicated way of doing try and except in python?
👍
This channel needs way more credibility and subscribers than it does at the moment. Best web dev channel in whole of youtube. Thanks Kyle.
Very helpful, thanks for the video!
Never forget to use return in front of resolve() or reject().

Awesome explanation which even a layman can understand. Thanks Kyle!
i started with the full stack course but have digressed 4 videos now in order to catch my knowledge up. thank you for referencing these videos that contain the requisite knowledge i didnt even know i was looking for!
I have a doubt:
In case of Promise.Race
Which task/process completes first we will get that response, then what will happen to other tasks/processes? They terminated or what?
Thank you
regarding async/await, this was also very helpful: https://tutorialedge.net/typescript/async-await-in-typescript-tutorial/
