Appreciate your effort you put to make videos. I Learned a lot from your videos over last 5 years. Many Thanks Kaushik :)

[@Java.Brains]

Thanks! Yes, it does take a lot of time to produce these kind of videos, but I am glad they help! :)

@@Java.Brains It really helped out many persons. I am also one of them. Following you since your jaxrs courses came out. Thanks a lot for your effort. Happy Independence day...

Your likes would get stuck in the event queue

[@u_ziben]

This is the clearest explanation of JS's event queue, call stack and event loop I have ever seen on KZbin. I really appreciate the effort you put into making these videos simple and clear. Great work JB!

[@nikhil1651998]

This tutorial taught Callback, Synchronous & Asynchronous and Event Loop in the most easiest way possible. Watched many long videos but only 8:26 seconds was enough!

[@codewithcreativecoder8834]

did you mean 506 seconds?

[@nwobodogeorge5370]

I have never seen a very clear, straight to the point explanations on event loop like this. Thank you sir.

[@PerpetualLearner8934]

This channel has quality written all over it. Online and offline put together, teachers like you are hard to find. All I can do is write a comment here to thank you. Keep up the good work! :)

[@smmehrab]

Wow! I actually studied JS Event loop before. As you said, many tutorials and JS Conf Talks helped me understand the concept better. But to me, the amazing analogy that you used and your awesome explanation, was the simplest one so far. Thank you so much, man!

[@devroy692]

OMG. I never thought the eventloop could be so easy to teach. Awesome.

[@veerenderreddychama3190]

I really liked “the waiter - restaurant” analogy to explain the event loop concept. Thanks!

[@vivekmishra5876]

This guy made my Weekend. Thanks koushik

[@sreid70]

I think you have the best videos on Javascript period. You take basic concepts and turn them into advanced concepts, yet I still understand what you are saying. You are a great teacher. Well done. Your "Introduction to Javascript for Developers" series is my most favorite Javascript series on KZbin. Very well done. Permanent bookmark:-)

[@khalidben9940]

This is the clearest explanation I have ever seen on youtube about this topic.so many long videos only complicating things instead of making it easy and neat.Java brains you have been always one of my favorite channels.Thank you for this amazing video

[@bernard2735]

Great, simple, clearly explained. Thanks mate.

[@user-cc8he7dy9h]

For the first time I saw how someone was able to explain the event loop with some kind of analogy from real life, I think this is what a lot of people on KZbin lack, thank you very much for your efforts!

[@kinstar]

sometimes the best explanations need to be in human terms 😅

[@ratgirltika]

This video has been incredibly helpful to simplify understanding of how event loops and call back works in JavaScript

[@rahulbeniwal2230]

I have seen explanations but effort you put to make it animated and real life example is great. Brain actually captures such things more easily. Thank you Java Brains.

[@zekss07]

I am so glad this video had no big circle in it. Thank you for finding your own way of explaining things!

Is it just a coincidence that when I was learning java and spring koushik was also into it, and I'm now learning javascript, he's also doing the same :)

[@Java.Brains]

Yup, definitely stalking your learning path. Too bad you caught me! :)

[@ravianand6351]

@@Java.Brains hah But seriously, you've helped me a lot, and many others ofcourse. I found out the java road map video to be very helpful. If you could bring a similar sort of video for javascript, it would be really helpful.

[@69k_gold]

Amazing explanation! But I always wonder how the V8 runtime knows when some API call has returned or setTimeout is done. Is there a separate listener thread whose whole purpose is to wait for asynchronous callbacks so it can add them to the event queue?

[@deepakarya5310]

thank you very much i have watched many resource and got so confused...this cleared all my doubt

Fantastic explanation, many thanks)

i heard that the callback in the que get pushed to the stack, only after the stack is empty, but does a stack ever get empty?
