Alert : The setter function in usestate hook should be used with a callback function. The setValue should be called like this. E.g. setValue((prev) => prev + 1) Also , instead of creating a new variable just write {value * 5} as node value. Done !

[@yuvrajsinghGurjar-eb7ko]

setvalue in callback on button click event

[@3clouds919]

Bro, but if we will write {value * 5} then i think values will go like 5, 25, 125... instead of 5, 10, 15...

[@prathameshtirlotkar505]

This video will exactly teach you how state is updated and total component is re rendered best explanation 🔥🔥

[@sandeepraju2507]

Thanks Hitesh sir for the great explanation. Here is what I understood as the summary for the benefit of everyone : If there is a state, and another field that you need in the component can be directly derived from your state, then simply use your state to derive the result instead of creating another state.

[@shashiKPD]

This cleared al lot of react doubts inn my mind. The fact that the whole App is getting rerendered never occurred to me. Thanks a lot for this video

[@sultangaming7336]

Lot of thanks sir for providing deep knowledge course and also interview series i request you to continue this series till we master in react.

[@RakeshBitling]

wow..sir this is what i was searching..this channel is excellent.. Sir is teaching excellent....

Thanks and welcome

[@RakeshBitling]

@@chaiaurcode thanks sir I am loving this series and preparing for interviews too.

[@Dev-Phantom]

Interview - this is a part of Life cycle method in react ---- when there is any change in the state the whole components will remount, means component will update.

[@VishalSharma-rn7mt]

Awesome, very simply, beautifully explained the concept Thank you so much Sirji 🙂

[@nishantsah6981]

few days back after watching your useState video I was trying to build a simple calculator where I used two variable in useState and common boolean flag (not a useState) ... when flag == 0 var1 will get a value and will turn flag = 1 else vice versa ... however it wasn't working... every time only the first variable was changing, then I also took the flag as useState ... it then worked fine ..... but wasn't able to understand why it wasn't working earlier.... Today I got the answer

we should not overengineer any code in react, or say use over resource of react. it becomes to complicated. just make it simple. easy to understand . Thanks sir.

Sir, there is a difference in both flows. The first flow involves multiplying first and then adding the main value, while the second flow involves adding a value first and then multiplying.

[@irfansaeedkhan7242]

best tareqe se samjhaya hai but agr wo kahay k value ko update na kro tb tou dosri state use krna must hogi na

[@devmittal29]

A question here, if we don't change value i.e. we don't write setValue(value+1) then the component will nt re-render and the multiplied value won't be updated...right?

[@relativelyrehan]

I have read on twitter once that learning react is learning useState and useEffect, and then learning how not to use them.

Bug Alert🐞🐞 : There is one bug with this code, when Hitesh sir showed the solution with two state variables then the multipliedValue was initially 1, but then in the second approach it became initially 5. It can be solved with conditional rendering, but there can be other ways. Also, it depend on what is the question asked on the first place (the requirements).
