Promises - Beau teaches JavaScript

[@meinsouza]

damn this is confusing...

[@sparshgupta8078]

"promises allow you to do something as soon as an asynchronous method or action does finish instead of immediately returning the final value the asynchronous method returns a promise to supply the value at some point in the future" this point clears it all! damn so clear explanation

[@ts8960]

makes 0 sense dude

[@ACantarela2]

I'm loving these JS videos, even more Beau faces in the thumbnails haha

[@eliweber2542]

You can’t use a word within its own definition...

[@KreativeHogwartsLegacyGUIDES]

the more complex the idea, the harder it is to understand the beau teaches java videos. earlier videos with easy concepts were some of the best videos ive seen on the worst internet, and im not exaggerating.

[@herolivesnu]

let doWhat=new Promise((resolve,reject)=>{ let multiply=(x,y)=>x*y add=(a,b)=>a+b arr=[1,2,3]; if(arr.length>1) resolve(add((multiply(5,6),10))); reject("sorry there is a mistake") } ) doWhat.then(result=>console.log(result)) doWhat.catch(err=>console.log(err)) /* I want to log 40 on the console with the above code, pls help by telling me what is wrong with the code*/

[@ekkehardehrenstein180]

Those promise example videos lack creativity and as a consequence don't make it very clear.

[@hikiyo13]

I love those tutorials so much

[@kaypakaipa8559]

Great explanation was so confused watching other videos. The Thumbnails are killer tho😂

[@sweeball]

Thanks for getting me here. This vid. has been very helpful!

[@ts8960]

terrible explanation

[@alainleclerc4523]

very confusing...

[@pradipta9345]

Beautiful ❤️

[@novanoskillz4151]

Love your explanations… but i think you chose the most confusing example possible to explain promises.

[@dannyiskandar]

thank you this really help clarify this concept ..promises ..promises ..ohh how can they be ..yeah :)

[@sasayaki]

I came to KZbin to try and understand promises better after my class sort of confused me. I'm trying to get as many different explanations as I can to see if one of them works for me. This was a good start on the syntax so thanks!

[@abdelrahman2348]

so if it's resolved then will executed and if not resolved or rejected catch will execute ? is that its logic ?

[@denoise_]

These thumbnails are turning into a Javascript horror movie.

[@kaypakaipa8559]

Illicit Industries 😂😂i tried to stay away from this video as much i could soon as i saw the thumbnail, but seems every other video left even more confused on wat promises are. Funny enough this guy explained well enough to get the concept.

[@tasoulman]

I think it is easier to user the fetch API. Am I wrong ?

[@aaronargottelopez3488]

DAnke

[@ahmadabdolsaheb]

I'm here for the faces :)

[@BeauCarnes]

😄 😁 😆 😴 🙄 🤔😋 😜 😝

[@oolumee]

When will be the time I can finally use my code not for good.

[@Anbualex]

OMG this may have made my JS game work better. Awesome!!

[@anag2125]

Love all your videos. Thank u so much!!! :D

[@thenecroyeti1]

The ordering of this series is a little off. Teaching switch statements then promises?! I bit of a leap there...

[@BeauCarnes]

That's just to keep things interesting for me. Eventually I hope to have a complete JavaScript series. Check this forum for the plan and to offer suggestions: forum.freecodecamp.com/t/topic-suggestions-for-beau-teaches-javascript-on-fcc-youtube-channel/89344/3

[@randomdeveloper6456]

Beau Carnes May I use your videos as reference to start a portuguese (my Native Lang) teaching channel ? I like the idea of learn teaching.

[@worldbosspf1]

thanks man I now understand this.

[@hpineroo]

This can be a way that several web services uses for 'undo' buttons work?

[@theluanvuong5886]

So, guys, when are the React and SASS courses come out ?

[@BeauCarnes]

I am planning on doing React. No plans for SASS as of yet since right now I'm just focussing on JavaScript.

[@andrewkiminhwan]

Im a fan Beau! and your slight boston accent?

[@BeauCarnes]

Actually I've lived in Michigan most my life. Some people have said I have an accent, though. I'm not sure where it is from. 😄

[@DevanSisson]

Beau Carnes same problem I have. Apparently I have an accent and I've lived in Utah my whole life.

[@naruto5437]

this was great...

[@jarrettklink4097]

I guess I'm a tiny bit confused. Where would you use this? As in, what situation?

[@grandpowr]

When you need to work on Asynchronous type of situations (like the final project Simon's Game). They're actually very useful because you can control with .then() how your code will work and can catch an error as well. If you still have issues then read the book "You Don't Know Javascript" they explain Promises and in which situations you use it.
