When we went into incremented function counter value was 0
So for i= 1 counter value get added by one and became 1
But due to for loop it went for 2nd iteration and value of counter (i.e. 1) is not retained and counter for the 2nd iteration is 0 again this goes on for all the iterations but when last time counter is incremented to 1 it doesn't go for more iteration and come out of loop and counter value (I.e. 1) is retained
Thanks sir :)
Thank you ! upload redux tutorial also.
Sir class component use karun ya functional
definitely use functional component... in future, class component is deprecating to functional component ,as the concept of hooks introduced in functional component ... its better to use functional component...
Hooks only use in function components
Sir my query is I want to update the product price on plus minus for example if my product price is 10 if I click on plus button it will sum up and give me 20 and same is the case with the decrement I am using react hooks.. please guide me
i didnot understand codeevolution vdo and landed here..this was the exact copy..lol
same bro
didn't understand here also
Sir Debugging or error handling pe bhi ek video
Sir , please make react.js website
100% copy of codevolution. But appreciable.
Instead of writing +1 I wrote +10 lol it's working fine 🤣😂
This example was to show you how for loop will behave in state
Everyone knows that can be done by doing + 10
But to show you how for loop behaves here this way was used
Plzz Mack vdo on redux
This is just copy of things already present on internet the main thing is reasoning why something works.
const incrementten=()=>{
for(let i=0;i
why sir you not use i in setstate
