After watching this video, was just curios and went to check which was your first video, when was it uploaded and hows the tutorial. You have come a long way in these 9 years. you have helped thousands of people, if not millions throughout your journey. I have taken numerous courses throughout my career live and online, Nobody has mastered the art of explaining the topics with such simplicity in short span of time as much you have done. I sincerely thank you for all your effort in making the tutorials. Wish you loads of luck in you personal and professional front. Keep up your good work.

[@benjaminaboagye9807]

I 100% agree with you @Ganesh. His explanations are how it should be taught both in class and in books!!!

[@frantzbazile1554]

Why is this not in W3SCHOOLS??!! Thanks so much @JavaBrains / @koushik!!!! Finally I see someone breakdown the many different ways of exporting in JS. Thx for making this clear as I'm coming from the world of Java

[@hyperborean72]

Could someone explain me please why after rewriting exports.add as (a,b) => a+b we had to change the call from another .js as var {a} by adding figure brackets? What had changed? It seems that whatever we assign to exports.add it has always been a reference to function, just different ways to write it - so why do we need to add {}? Probably it somehow let us call imported function no as add.add(x, y) but as add(x,y) - but why?

[@LijoMLoyid]

An object is returned from the add.js file. What he is doing by using {} is destructuring the object which is returned so that add gets the value of the object returned. So he is able to call add(10,20) directly. Just look up "JavaScript Object destructuring" in google and you can find more such examples to get a clear understanding of the concept

[@saucy05]

This dude is the best coding teacher on KZbin. He just has a way of breaking things down to the basics to make them digestable.

[@channel23653]

// var exports = module.exports; this line transformed my darkness into the light. 💡

[@a_maxed_out_handle_of_30_chars]

thank you :) 8:20, this is what I had issue with

[@AnanDNavalar]

Team, What happened?? No updates after these tutorials. We all waiting for ur upcoming sessions

[@narayanamt9534]

Thanks, Koushik. You have demystified JS. I recommend all beginners should watch this video to get a better understanding of the subject. Keep going!.

[@imyounick]

Please tell me why Exporting individual functions is better than Wrapping all function in object and then exporting

[@aditya-xt4it]

thank you soo much I wasted almost 10 hours about this topic and finally you cleared my doubt thanks a lot

[@samtheglamurai]

I'm in a coding bootcamp and was really hung up on this, then I found this video and it helped me understand sooooo much better! Thanks for your thorough explanation, it saved me!!! 😅 Totally had to subscribe!

[@graemegibbings6121]

Wow. Finally someone explains things in a way that makes sense. Thank you so much. Glad I found this video

[@jjanchovi8568]

you explain everything so well! Thank you sir !

[@virender288]

Thank you so much to makes topic understandable for beginner like me sir huge respect best wishes :))😇

[@JayTheMachine]

Very Very Very Helpful (with capital V and capital H). Thanks!

[@rolandovillcaarias5112]

Thank you for those clarifications. But still confused why you typed { add } instead of just add.

[@itzblinkzy1728]

Great explanation sir, thank you so much.

[@doriandoussain1528]

Sometimes indian guys are hard to understand, appreciate the time your take for be clear and understandable, thx.

[@jaleotech5918]

Bloody convoluted explanations. If you're looking to learn JS and node find someone else to learn it from. Utter nonsense.

[@elvispontes4165]

Thanks a lot. One question, why do you use var on your examples instead of const or let?

[@theSwomry]

for someone who seems to be _really_ good at programming, you sure type like a 4th grader. (not hating lmao)

[@vickycoool13]

Seems add function in first.js is not working properly. When operatorsObj.add(10,20) is getting called It should return 30, but its returning 3 and it must be after Hello there, Koushik!. Please clarify me if I am not getting it properly.

[@elroi6289]

But what if I have over 30 functions in the module??

[@jagannathkv9942]

can i use export default to export a function and us the import to use it in another file?

[@nevinkuser9892]

The code at 10:40 looks beautiful. So clean!

[@rouabahoussama]

in the add.js file the console.log(add(1,2)); is executing each time you call require("./add.js"); which is not what you are intended to do by calling it from first.js you call : // this is code from first.js add(1,2); // here you don't log the result to the console please be careful peace.

[@sbszcc]

you're right, I made the same analisis, anyway is undeniable that it's an excellent course

[@rakyatjelata3614]

About 1.2 is true?

[@LORDFARQUAADIUS]

Very clear, thank you!

[@naseem5622]

sir thanks a lot for this is the perfect explanation

[@Jacketsmargiela]

you sir just earned yourself a subscriber

[@thandolwenkosinzimande818]

Thank you for the great tutorial.

[@srinidhikoundinya18]

Sir Please Explain the difference between using require and import in javascript

[@izeoguandrew5358]

Youre simply amazing

[@vidhanchandra3698]

So whenever my manger says Dude why don't you upgrade yourself I visit JavaBrains and mission accomplished :D :D .. Kaushik Sir, something in AWS or GCP is the next thing which we all are expecting from you ..Hope we will get it soon... Thanks.

[@smartguy3k]

great video. Thanks.

[@vivekberlia8582]

Please explain es6 concepts also

[@sreid70]

I saw a post on StackOverflow that basically said this: module.exports = {}; var exports = module.exports; If you just imagine that is at the top of every module you make automatically, it becomes easy to see how the module system works. Great video, thanks.

[@ZoomAnimationHere]

Concepts are totally clear :)

[@peterabiodunokusolubo1541]

You are simply the best

[@jacobyako]

Hands down best JS and Node.JS understanding on KZbin. Others always say just show you the code, but he shows the details which helps people learn and encode in the brain not just memorize.

[@nevinkuser9892]

Wow. I couldn't find this great of an explanation anywhere else on the entire internet. You did a great job! Thank you. 🙏

[@codegate615]

Javabrains has a gift for teaching. Only problem is he hasn't covered more coding topics!

[@iqboss2008]

Can you explain why you said exports.add is the recommended method over module.exports

[@goksnarasi]

Thanks Very much

[@crs2236]

Hai sir can u explain active directory and LDAP authentication spring boot can u explain real time example

[@Medi0cr3-]

nice job man, this clarified things I thought I was decent at, but helped immensely in my project.

[@brunosastre1948]

Thank you very much for such a great and detailed explanation! :D

You are the best teacher 😊

[@namesurname4708]

TY so much Bro ;)

This was really helpful to see beyond the various ways of notations and why syntax is used one way or the other. Thanks

[@abhijitmohanty7818]

What's your view on IT recruitment in upcoming days

[@roshanjha5390]

i had a one question, we are calling add(10, 20) from first.js but it is still returning the value of add(1, 2) defined in add.js. would anybody please help me out with this, i did not understand.

[@roshanjha5390]

i got it my mistake

[@sanketsultan2348]

sir waiting for more videos on node js

[@glennadams7047]

Best explanation!!!

[@kamalhm-dev]

will this also work on js?

[@vickycoool13]

Seems add function in first.js is not working properly. When operatorsObj.add(10,20) is getting called It should return 30, but its returning 3 and it must be after Hello there, Koushik!. Please clarify me if I am not getting it properly.

[@harsimransingh5305]

we are not printing returned value in case of operatorsObj.add(10,20) and 3 is printed because of console.log() in add.js

[@sandeepsundaram5577]

simple clear and crisp

[@fratell]

Thanks

[@DeepakGupta-hj2dv]

Outstanding explanation sir ...Thank you so much for change my life this series 😊
