JavaScript Promises ‍in 1 Minute #shorts

No way, you managed to explain this so quickly with such a good explanation. You truly understood the concept.

Dude 🔥 😂 just bought me as a subscriber bcuz I understood thus immediately 😅

thanks man good explaning

uggh what a superb explanation! Took me months in my uni days to get this

You are exactly looking like a Rishi Sunak sir

Damn, you are good…

JS and TS is really a stockholm-syndrome kind of vibe huh

Careful, because of javascript's single threaded nature, any hard waits will still block the thread. For example, try putting a sleep() call in the promise

Isn't async and await doing the same stuff?

For straight 2 seconds I thought this was Rishi Sunak.

Loved this. Pls make more. Better to watch this than all the crap on yt

Nice 👍

async await?

you could have just return weather from getWeather it will also be a promise , no need to wrap a promise inside a promise

async await >

hahahaha thanks, I'm learning springboot, but I was trying to learn some JS to build very basic UI, I was checking this very specific subject with some some examples but didn't quite made sense, but your example gave me a good starting point, thanks xd

Well explained👍

that take for resolve reject as then and catch, i never thought of that when learning promise since they all use resolve and reject. could've understood it faster if they did it as then and catch in teaching materials/videos/documentations

Nah I just do
return true

sounds like python but worse...
why tf do people even use it

❤

Nice

As an Iranian, I am proud of you, Sina.

Its just so much cleaner to avoid all this, make the function async and use the await keyword

omg i have learned this sh*t for 3 days and now I understand it in 1 min

Great explanation.... But just make the code actually fits the screen next video.

You 're amazing that you can give an explanation of promises in just 1 minute🙏🙏🙏, thanks Sir

now do with async await

I.... understand 🙃
finally
ffs

but we could do this with async await

what is the theme?

Async Await left the chat.

But really nice explanation in this as well as the full video.
Give the link in comment and pin it

I swear JavaScript too my looks like {([<>])} the end of a function is mostly like )};

Then over other languages will end like
}

Calling resolve and reject as then and catch feels like it would make learning about promises a lot easier. And I say this as I work on the monster I created some time ago that is a recursive async and promises stack used to fetch info from different apis and merge them together to start new requests, with some apis being limited to 10 records at a time while I need them all (about 40)…

Better use async await :)

who wouldnt want to see "jim sarbh" teaching javascript

Great explanation... Link for full episode please

I hate the explanation that something is wrapped in a promise because it takes time. Iterating to 1e12 takes time yet you're not going to put the loop in a promise.

Promises. Uh huh

Disadvantage of promises: callback hell

Try to solve Hanoi Towers with promises. Every next promise is more clear to the end position

Use async await

We need a better client side script language. Javascript has been bastardised beyond belief to the point its almost unusable now with writing endless closures around things.

subscribed. Although I am a Java developer

This is misleading, resolve and reject are not synonymous to then and catch.

Please do RxJs

Think we can just use async await to get the api response 🤔.. not sure though

Please tell me how I get those colors in my vscode

JS is weird

I’ve been struggling with async for days, but when he said that a Promise takes two parameters, “then” and “catch”, but that they’re called “resolve” and “reject” I was like OH SHIT! Now it makes so much more sense
