Async/Await in JavaScript | JavaScript Tutorial in Hindi #59

[@mangalmangalam]

Harry bhai you are not a programmer....you are a library of all programming languages . Thank you for all the lessons you provide us.

[@CodeWithAryan_]

Really , Harry bhai is genius 🙏🙏🙏🙏

[@deepsachapara]

​@@CodeWithAryan_​ Yes you are right.

If you plan on making a NODE JS course, you'll be my hero!!

[@GoSleep07]

Agree 💯

[@devtttt]

@@shivampandey3897 thanks but i don't have laptop And node isn't working on phone 😭

[@MaazShaikh-ji2fq]

Node js is just used to run javascript it is not a language. You can search for backend development courses. Or if you mean npm then you can sear h videos for that too.

[@ShivamYadav-cc8pf]

He is still a hero!! buddy.

Harry Bhai Pahli Baar Itne Acche Async/Await Clear Hua Hai....... Wow For me its a magic

[@vikranttyagi6091]

Harry bhai we also need a proper guide on NodeJs/Express Js also .This gonna be a big step ahead for those who wanna be a full stack developer.

Harry knows the student's nerves! Love the way he is giving back to the community. Loads of Love from Pakistan. ❣

[@christosuster2924]

This is the best explanation of async/await I have seen till now and it has helped me a great deal. Thank you very much for all those examples.

[@samirrobin3524]

This is really one of the best JavaScript course...Thank you so much Sir ❤️❤️

[@Swabhimanc]

I know I am a little late for this. But on around 13:00 when you said that p1 will execute after 2 seconds and p2 after 5 seconds. It is incorrect. p1 will execute after 2 seconds and p2 will execute parallel to p1 and fulfill after p1 after 3 seconds. await keyword is not stopping the promise from getting fulfilled. If you setTimeout of p1 greater than p2, then "Fetched Bangalore Weather:" will get immediately executed. Thanks. And excellent course Harry bro

[@harshitgupta6661]

Ye prob mujhe bhi thi

[@theannonymous1430]

you are wrong i just tested it, i set p1 value to 4 second and p2 value to 2 seconds to see what's gonna happen, and because of "await" keyword p1 takes for 4 second and p2 takes additonal 2 seconds to complete, in total 6 seconds not 4 seconds which means "await" keyword make your promise work synchronously.

[@prakharsrivastav4550]

Hi harry, Thanks for this series. I am following a web development course. The topic of promises, even though taught was going over my head. Thanks for clarifying. I appreciate you taking your time.

[@ramprasadyadav9303]

This javascript playlist is Really Awesome !😍😍😍😍😍

[@ekanshsharma1309]

Solution of Problem at 13:45 async function sum() { let a= new Promise((resolve, reject) => { setTimeout(()=>{ resolve(10) },2000) }) console.log("Fetching Value for a1"); let a1= await a console.log("Value for a1 is fetched ie:- "+a1) let b= new Promise((resolve, reject) => { setTimeout(()=>{ resolve(20) },4000) }) console.log("Fetching Value for b1"); let b1= await b console.log("Value for b1 is fetched ie:- "+b1) let c= new Promise((resolve, reject) => { setTimeout(()=>{ resolve(30) },6000) }) console.log("Fetching Value for c1"); let c1= await c console.log("Value for c1 is fetched ie:- "+c1) let d1= a1+b1+c1; console.log("Value for d1 is "+d1) } sum() // Like if it Helps you so that i can know :)

I was that much engaged in the video that when you asked "kya harry and cherry ko bhi await krke dikhau ?" I literally answered out loud.....

If some one has not understood Async/Await by this video then first watch old Async/Awaitlecture of code with harry. Much simpler example is given in his old video then come backend re watch this video.

Day59#100DaysOfCode with CCODEWITHHARRY, JavaScript, today i learned about await and async function in JavaScript.

[@alpanakushwaha9109]

An Async function always returns an Awaited Promise. Other values are wrapped in a promise automatically

Very Nice Tut🔥🔥

[@travellingsongs6120]

I want real world example with the specific project..

[@Hiteshkumar-fn8gi]

I observed one issue here. 13:40 Delhi weather printed after 2 seconds and bangalore weather printed after 3 seconds from printing delhi weather. Try setting both timeouts to 5 secs and you will notice both delhi and bangalore weather prints at the same time after 5 seconds, instead of printing first delhi after 5 secs and then bangalore after 10 secs.

[@gloryjaw4327]

I don't think that's an issue, since both of them are called one after another (which almost at the same time), it is supposed to happen. If you want bangalore weather printed after 5 seconds from the completion of delhi weather, you can just write the await for delhi weather just before the settimeout of bangalore weather

[@DHRUVINVEKARIYA]

maja aa gaya harry bhai async await padh ke....it is like controlling RAM memory in actual sense

async function func1(){ console.log("hello func1") let p1=new Promise((resolve,reject)=>{ setTimeout(()=>{ console.log("p1 4s") resolve(4) },4000) }) let p2=new Promise((resolve,reject)=>{ setTimeout(()=>{ console.log("p2 3s") resolve(3) },3000) }) await p1; await p2; } func1() o/p : hello func1 p2 3s p1 4s shouldnt the o/p be hello func1 p1 4s p2 3s

[@murlimishra6502]

Question - JavaScript is a Single threaded language, then how multiple async. functions can run parallelly. ??

[@VivekKumar-tk5tt]

hats off to your teaching brother, but I don't think the bangloreWeather promise is waiting till the delhiWeather promise is resolved means they both are running parallelly. In order to run the bangloreWeather promise after the resolution of delhiWeather promise, we have to put these promises inside of a function and await those functions instead of awaiting the promises. Like this:- let weather = async () => { let weatherDelhi = () => { return delhiWeather = new Promise((resolve, reject) => { setTimeout(() => { resolve("21 deg") }, 2000); }) } let weatherBangalore = () => { return bangaloreWeather = new Promise((resolve, reject) => { setTimeout(() => { resolve("26 deg") }, 5000); }) } console.log("Fetching delhi's temp...") let dw = await weatherDelhi() console.log("Delhi temp: ", dw) console.log("Fetching Bangalore's temp...") let bw = await weatherBangalore() console.log("Bangalore temp: ", bw) } console.log("Welcome to weather control room:-") weather() Please correct me if i am wrong !
