To the point and no extra useless stuff taught only what is needed. just what i was looking for. Thank you So much.

Just 10 mins and the way you explain things is perfect. I've watched countless tutorials before and you really explain awesome.

Absolutely awesome. Finally someone who can explain things in the right pace and kept me engaged for whole video.

I’d love to watch it now, but it’s 2am and I know I’m going to get brain blasted. Saving for later instead ;)

A very nice and clean explanation of difficult concepts in short video. Thanks so much Vishvas. You are great teacher indeed.

I love the way you explain difficult concepts in a very simple manner

Hello Vishwas! I'm a huge fan of yours You videos are really high quality and you have the skills to explain complex things to others in a very easy way I have learned a lot of things from you Thank you very much for all of this quality content This is better than most of the paid ones as well Hope you get more subscribers soon !

In this code, th e outer function returns a reference to the inner function by using return inner. This is called returning a function as a value, or returning a function reference. If the outer function had used return inner(), it would have returned the result of invoking the inner function instead of a reference to the function itself. This means that the fn variable would be assigned the value returned by inner(), which is undefined since the inner function does not return anything. By returning a reference to the inner function, we can assign it to the fn variable and then call it multiple times using the fn() syntax. This allows us to create a closure where the inner function retains access to the counter variable even after the outer function has completed execution, as explained in my previous answer. So, in summary, return inner returns a reference to the inner function, which can be stored and invoked later using the fn() syntax, while return inner() would have returned the result of invoking the inner function immediately, which is not what we want in this case.

Thank you for this crash course and async js I truly needed them.

Interviewing next week and need a refresher! Thanks for this!

Teacher of the year! 🥳 I appreciate that it seems that you know what questions we are going to ask ourselves and you cover every case.

Superb! Great clarity and understanding. Thanks.

I finally get curried functions! Thank you!!!!

Thanks a lot it refreshes the concepts in very clear way. Great teaching. Thanks Vishvas.

thank you, sir, I wanted a course like this only

Wow... This is great! Hope to finish this within a month..

First part was clear, and superb, this video is quite confusing, mostly because of impractical examples which do not represent real scenarios. Must change at least the currying example.

Thank you very much! It would get better if you could add more real world examples after each chapters.

Great job, thanks a lot for your effort :)

I want to point out a mistake on 40:10. The Object.create should be before adding new methods. In example above, fightCrime() is the new method, if Object.create is after fightCrime(), that method won't work. You only called getFullName() method in the video so it seems everything works fine. Prototype object cannot be assigned after new methods. All-in-all, great tutorial, keep it up!!

it was very helpful thanks a lot now i am waiting for your next crash course on js

In currying example, the innermost function does not return a passed-in function instead it is returning the result of the passed-in function

Thank you so much, you help me a lot!

One of the best resources for learning javascript.👍 excellent beginner-friendly examples.

Can you make a video on javascript design patterns? It would be very helpful .

Amazing tutorial Vishwas. You rock man.

Best refresher again Mr Vishwas, thank You sir :)

hi viswas sir please start a full fledge gatsby series like your nextjs series we are waiting for your series

When you want to return a function from another function and create a closure, you should return the function itself without invoking it. In other words, you should return inner; (without parentheses) and not inner(); (with parentheses). Returning the function without invoking it allows you to create a closure, which means that the inner function retains access to its containing scope and any variables defined in that scope function outer() { let counter = 0; function inner() { counter++; console.log(counter); } return inner; // Return the inner function without invoking it } const increment = outer(); // Store the inner function in a variable increment(); // This logs "1" increment(); // This logs "2" Without closure function outer() { let counter = 0; function inner() { counter++; console.log(counter); } return inner(); // The inner function is immediately invoked when you return it using return inner(); } outer(); // This logs "1" and returns undefined outer(); // This logs "1" and returns undefined

Great!

I'm at the right place to watch this video💪

This is still a good tutorial!

I didn't properly understood the prototype inheritance part while the class part was simple as I have been doing java and c++

Greatest teaching ever. Give this man a Grammy 16:43

how did you bind the clg shortcut with console.log in vs

Hi bro. Will you upload full javascript tutorials for beginners

When I am trying to get batman.fightCrime() it is saying that fightCrime is not a function. Can anyone explain why? When I remove SuperHero.prototype = Object.create(Person.prototype) it works

Thanks:-)

Thanks Vishwas

Best content by best instructor👍👍

To undestand closures, just imagine inner function as a normal function in global scope which is outer function. How i get it is like in global scope when you increment something with function it stays to that value and for inner function outer is global scope.

video on cypress and jest plz

can you do a crash course on TypeScript?

while i wrote closure code it showing sum is not defined in terminal

I have noticed you are given an example of the character of the Breaking Bad web series 😂 though I like your react, Js etc tutorials.

Wishwas update Storybook course pleaseeee please :)
