This is why closures are important in javascript #shorts

You often need to use a closure to create private state that only a function knows about. Here is an example of when you can use a closure.

Those who code in React would understand better. There are class components when we use oop and there are function components that use functional programming. In function components, when we declare variable inside a component or create states using useState(), we are essentially taking advantage of the concept of closure. Every time i call the function component somewhere, each one would be a seperate instance of that component. And no oop used for this to happen.

Well this is why we have something called class 🙂

Nice break down! Your shorts are so well spoken and concise too

After watching tutorial video reading the documentation this simple and crisp video is much needed!!!
Thank you sir!

Omg!! Thnk u so much I've been struggling to understand closures really this just made it clear it all.

[NuclearJeday]

Okay, as a person not familiar with js, the only question I had the entire time is: "What, the actual fuck?"

[katalysmus]

Javascript has so specific issues and so specific solutions for those issues its *almost* beautiful

[sourabhkulkarni]

Thanks for explaining closures in less than a minute

[telugucodingguy]

Do more on async promise and call backs

[mitkomilev]

Thank you for this video! Really intuitive explanation, subscribed!

I'm just getting started with React, and have actually been using this without realising 😅..

You are the man bro, You explained this in a very simple way...HUGE RESPECT 🥰🥰🥰

The important thing to understand is not “closures are THE way”, but “closures are A way”, and this little example is an easy way to play with them.

To understand what is happening in JS you must understand how it’s closures and objects work, among many other things. Ignoring one (or worse, framing understanding of JS objects in terms of more typical OO languages like Java) will leave you confused when you inevitably run into code using that other thing. Code in a way your brain understands, but be able to read and understand as much as possible.

I just learned what classes are and how they work and this thing looks like a class... are classes something newer or older than closures?

[vsowill]

Thank you! I was looking for this the other day! 👏👏

What extension let’s you auto comment the console log? That’s awesome

[pcostarg]

This is one of the best explanations about closures I have seen. Simple and to the point. Most of the time people will lose themselves with technicality.

[rodbrowning]

What I most like of this channel is that it goes direct to the point.

How do we get the value of the count in this case? Do we return an array of 2 functions one for setting count and other for fetching it or is there another way to do that?

I didn't understand what's the problem in the example counter program was just working fine...why we can't have that as external variables
