"The callback function gets put to the back of event queue". That's so refreshing!

Happy Teachers Day !! One of the best teacher's !!!

[@romanazeem3098]

Best and the most hidden topic using JavaScript. Great Content

[@CVenture]

Great .. Can you pls explain the differences between async await, promise and call backs? It confuses all the time..

[@ranikontham5573]

If we call a function inside another function then it is call called back.
Promises are used to handle call back hells they have 2 parameters resolve, reject. To handle resolve we need to use .then to handle reject we need to use .catch
To handle the promise chaining we will use async/await
We need to use these async/await jointly
for example
async function test(){
let data1=await func1();
let data2=await func2();
}
async > promise > callback
I hope you got some idea now

There are so many famous tutorials out there that teach wrong things.
Your tutorials are the real thing ♥️.
Please create a complete Javascript course.

You explaine very well...

[@smmehrab]

So well-explained! Thank you!

Happy Teacher's Day Koushik !!. Thanks for your Amazing Content.

[@sreenathmca]

As usual you are great in explaining complex things in simple way...

[@KDOERAK]

great examples; I learned a lot. Thx!

[@MustafaAli-xj6lq]

Best and most simple video so far

[@vivekmishra5876]

Great teacher always simplyfies the explanation like you

[@yashpandey9550]

Really liked the introduction to web workers. Quality content as always 🙏

[@khalidben9940]

Great as usual.I learned a lot of java concept from you now I am learning Javascript advanced staff from you.I am grateful.

[@sundaramjha1776]

Really Awesome, i always recommend ur channel to other people.

I really like your didactic approach.

[@vsowill]

Man this is gold!

[@smartydude2157]

Thank you so much for such informative video 😊.. Please make playlist of Data structure and Algorithms using Javascript will feel more thankful. Because there is no such playlist to learn Algorithm using Javascript.Thank you 😊

[@praveen27100]

It's Great!!! Thanks a lot . You are amazing...

[@FahadKhan-qj3ej]

Thank you so much.

[@bourairabdullah1287]

Please create tutorials for Docker and Kubernates, this topic is widely used and new !

[@smartguy3k]

Awesome!!! Thanks.

[@RAJATTHEPAGAL]

setTimeout(fn, 0) and setNextTick are effectively same right, appendig the function to end of pending function callback queue 🤔. Although for anyone reading there is a setImmediate 😐 which actually happens to place the function call for the next tick and not the end if event loop. 😌 Small nuances of nodejs api

[@ashishchourasia2830]

Great explanation, but I have some doubts: In strategy 1, why can't we just call the lessimportantWork() after the moreImportantWork()? why to use setTimeout altogether?

[@garbagemail9089]

hmm....good question AMC

[@elmersbalm5219]

Js works in a loop. A good candidate would be user interaction and screen update functions. Not terribly important but needs to be small, quick and out of the way when* needed.
Let’s say you’re updating a cart to a busy server, not an intensive process but can be slow. You still need to interact with the user and that all happens in the event loop.
* when the loop magic allows time for them

[@NicDHa]

great!

[@shubhampatel7870]

Hi Koushik, can web workers communicate amongst themselves? webWorker1 and webWorker2 for example

[@pranab1989]

Can you please tell us what software you are using to edit video.

[@AnandKumar-ro1yd]

Sir, have you created multithreading and concurrency tutorial? Please create tutorial in this. These concepts are hard to understand

[@enki1939]

why do we not just move the lessImportantFunction after the moreImportantFunction? Feels like that would be more of an intuitive way that doing the setTimeout(fn,0)?

[@ranjeetthorat1318]

Use case one. just reorder function call .no need for settineout

[@rushabhmandvekar4411]

Hello Sir, Please make one series on Nashorn JavaScript. The amount of contents on internet are very very less. Please address this. Thank You..!!

[@pragyan394]

I always used setTimeout with 0ms as the time, but only now do I properly understand what it's actually doing

[@vivekkoul4428]

Can anybody tell me pls what is the bug in the 2nd method?

[@RafikBianconero]

So at the end is Nodejs a similar Java runtime ? since web workers were lunched ? at the end the difference between Java ecosystem and Javascript is only the fact that JS is a loosly typed, flexible language ?! It seems like there is a mimication or recreation or lets say highjacking of the Java ecosystem and a community revolution against Oracle passed supremacy, a community revolution supported by Google through v8 engin... ? is it right ?

[@vivekkoul4428]

Is event loop concept also in javascript?

[@chieeyeoh6204]

9:26 when you explain strategy 2
function processArray(bigArray, start)
I think it will only execute once, because right after the forloop, start get increased by BATCH_SIZE while BATCH_SIZE remain the same the whole time

[@ShubhamKundu_]

He told that there is a bug in the code, the condition should have been "i < start + BATCH_SIZE" instead of "i < BATCH_SIZE"

[@vivekkoul4428]

How it will be start + batch size? Batch size is the size of the array and loop can't exceed batch size.
