// Promise = An Object that manages asynchronous operations. // Wrap a Promise Object around {asynchronous code} // "I promise to return a value" // PENDING -> RESOLVED or REJECTED // new Promise((resolve, reject) => {asynchronous code}) // DO THESE CHORES IN ORDER // 1. WALK THE DOG // 2. CLEAN THE KITCHEN // 3. TAKE OUT THE TRASH function walkDog(){ return new Promise((resolve, reject) => { setTimeout(() => { const dogWalked = false; if(dogWalked){ resolve("You walk the dog 🐕"); } else{ reject("You DIDN'T walk the dog"); } }, 1500); }); } function cleanKitchen(){ return new Promise((resolve, reject) => { setTimeout(() => { const kitchenCleaned = true; if(kitchenCleaned){ resolve("You clean the kitchen 🧹"); } else{ reject("You DIDN'T clean the kitchen"); } }, 2500); }); } function takeOutTrash(){ return new Promise((resolve, reject) => { setTimeout(() => { const trashTakenOut = true; if(trashTakenOut){ resolve("You take out the trash ♻"); } else{ reject("You DIDN'T take out the trash"); } }, 500); }); } walkDog().then(value => {console.log(value); return cleanKitchen()}) .then(value => {console.log(value); return takeOutTrash()}) .then(value => {console.log(value); console.log("You finished all the chores!")}) .catch(error => console.error(error));

Finally, I understand PROMISES. Thanks

Take out the trash "is really quick" => open the window/door - throw the trash - close. 🙊 .... Thank you! Getting closer to understand. (The value in the end is a bit "confusing", but I will make some studies and samples.)

Wow, after watching many videos finally i understood. Thanks.

Your video made promises clear in my head. Thank you for your effort.

It is the best explanation ever. Thanks

This is super helpful, last night was having trouble wrapping my head around this but this video really made it click! Thanks man!

Man i love you sm i had such a hard time understanding callbacks and promises

The best tutorial on promises. Thanks mannn

Bro, you rock. Thanks for the video!

Very good thank you.

Thank you, it was very clear and simple.

I finally fully understood. Thanks man.

really helpful. Thanks

You are great!!!! Thanks a lot

Wow thanks a lot. I was struggling to understand but now I do.

Thank you very much

Thank you

The way of your explain is Awesome #BroCodez Thank You

Can you please explain the code you wrote inside the then() method. What does it do and why are we creating the arrow function with value parameter and how is it able to access the resolve value

Yuuuhh, killed it mann

THE BEST EXPLANATION

Youre a savior man!

Thank you, it really helped me

You are awesome

The best!

i just searched about this tomorrow and you uploaded it today what are the odds ;)

OO LA LA

If the code is asynchronous why does the first reject prevent the other functions from being executed

Honestly I find the "pyramid of doom" less confusing than promises

I noticed some tutorials will create a variable equally a new promise kinda like this "var p = new Promise((resolve, reject))" ... in your example you returned promises, is there a preferred way or this situational ?

Can you not method chain instead of returning the values of the promises?

where was this when i was banging my head against the wall learning this ;.;

I understood it, but you made it a little unclear than it should have. Using .then.then.then without returning anything would've been a little clearer maybe, but there are a few other ways.

how he do this 1:50 ? This little picture ?
