This React Trick Will Blow Your Mind 🤯 

Finally the key makes sense to me

There are lot of exmaples including this is in the react docs. So, people should complete them first before jumping into react fancy clone projects😂.

Hi, according to my knowledge every componant by default has key that is given by react but some times this key will not applied so that issue occurs then manually have to pass key Is

brother aapki video ka thumbnail kon banata hai i need to contact them please

This video was there bro already on web dev simplified few years back. Still no problem you can still go for this type of videos too, bcoz not everyone will be aware of it. Also I liked the second example.

I did not know this use case for the key prop. I though it would only be useful for a list or array of components and to differentiate between their state. Thanks for the amazing and concise explanation.

I am subscribing for this…👍🏻

Awesome 👍👍👍

thanks sir

I think you have to make a daily video on a issue or a component, Great ❤

Thankfully we've subscribed to wds

i have a query, if each selected play value maintain state mode, when even selected event change, example if player virat have score 4, then change the player to rishabh now rishabh score 3, then back to virat, score should be 4 (maintain the state of that player score)

Wow just wow, I did't now this till now, this could have save my hours of debugging 😑😑

subscribe after watching this video make more this kind of videos

Very Interesting. Thank You

actually I am aware of this things but can't get up with class components, even I haven't tried to code them yet 😅

I was rewriting the code for 1 week due to this and now I know this my 1 week work seems waste with 1 key change in the component. Thank you so much

I always knew that whenever props changes the child component rerender. So why its not re rendering. Yeh dom tree ka concept kdr se agya. It should have re rendered 😑

Ok but how to store the local score value in memory so that it doesn't get refreshed to default every time the props change?

Finally got to know the importance of key

Very well explained! I got the key, finally! 😅

Thanku sharing knowledge trick

Sir make a course on Microfrontend With React 🔥

very interesting, I am a React developer I never knew this.

I am at 3:07 and the problem is key you have to define key to your component

very nice , we learned something from your bug

bro you does lots of useless talk. kindly try to talk less and to the point and code much

Please make a video on debugging large code based on browser

For this case we can also set default value to state on umounting of component in the return of useEffect

Vai. Your explanation is really awesome.

Ye key to bohot important nikli ❤

nice video. bring more video like this.

My guess for the challenge was correct

Why you didn't use effect?

Please make full mern stack course

tabhi react hr bari loop ke andar key leta hai

Are bhai 😅😅.. I am beginner but mujhe laga kuch aur khas baat hogi. Ye to pehle se hi bata tha.. Aur agar koi backend se aaya hai frontend to usko pehle se hi bata lag jayega

super excellent

Ohh now I get it...

Unique video

Please Piyush complete the aws series with all the aws services from developer standpoint

WOW!!!!

I have been working on React from the 3 years, but Today I got know this thing. This is something very different.

Bhaiya please make Nodejs Backend Project in Microservice Architecture as there are no good resources for that especially updated for 2023🙏

Thanks you Piyush bhaiya for sharing ❤

Literally mind blown, so cool to know this, it's definitely a tricky bug to slove. Thankyou for this🎉.

Sir, I want to ask you one thing Is your NodeJS playlist complete? like I want to learn Node and express so I'm thinking of following that playlist

I was using key prop for a while but don't know exact use of it. Thanks for sharing the information. 👍

loving your work

I was really fascinated by the u handled the problem. I was trying to solve it keeping the score state in the parent component and setting it to 0 on button click. So, whenever there is a click event on the button, the score will automatically be set to 0. Really helpful video sir...

and all of this because of diffing.... 2:48 like dekhein jb reconciliation ho ri hogi jis ki output mein fiber tree bny ga to sth he diffing b ho ri hogi jis ka simple concept hai k ya elements ko track krta hai by their position or agar ek element div hai to bd mein b wo div hai span nahi to wo re-render ni kry ga
