This React Trick Will Blow Your Mind 🤯

[@abdussamad0347]

Finally the key makes sense to me

[@prasadsawant7]

True 😂

[@semicolon6499]

😂😂😂

[@priyanshsharma8411]

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.

[@codetechygoon]

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.

[@a000000j]

Finally got understanding of key prop y it's needed... thanks brother

[@ManojKumar-ud4ye]

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

[@aakashjadhav327]

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

[@aasifkhan1545]

Appreciating your approach to explaining the problem and its solution, Thank you for sharing this with us.

[@sayantanichatterjee2445]

Sir aap bohot achhe se concept clear kar dete ho 👌👌

[@vikaskumar7019]

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

[@itsworldtours]

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

[@umangdubey6200]

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

[@fayyazali7246]

but i think key is better solution

[@rashidsiddiqui4502]

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...

[@imPrathamDev]

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

[@kumaramit04-q6c]

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😂.

[@pankajsingh7223]

react k official doc mai esa ek example hai sayad se thank you for more clearification ❤

[@Dev-Phantom]

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

[@sulaimanshabbir]

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

[@avi_5827]

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 😑

[@continentsports]

Nice sir

[@sayeed__ajmal]

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

[@sayeed__ajmal]

Aur agar console check kar lete to wahi bata deta ki bhai key daal element me 😅
