Hi first of all thank you so much for this video it's you who cleared my doubts. Now I am curious how can we use useCallback if we are sending setAdd or may be setCount in Child component. In my project I have above situation. Thanks in advance

[@shrawansingh9142]

sab kuch ezepzee kr diya Yoshinaga mam (Sinchan's Teacher)

[@blackmamba3984]

useCallback is a React Hook that is used to memoize a callback function. This helps prevent unnecessary re-creations of functions on every render, which can be important for performance optimization, especially when passing functions as props to child components that are wrapped in React.memo or when the callback is a dependency of other hooks.

[@srikarravoori124]

Thanks for the great explanation. Your videos are short but has great content.

[@yoshitajain0812]

Thank you 🙏 😇

[@manyfacedlearning8102]

this is a good example for use callback and useMemo very easily understood

Perfect job mam, Thanks a lot😊

[@sarthakdas5859]

One correction: React.memo and useMemo() are not the same thing. You got that wrong in this video, but the overall explanation was excellent.

[@lakshmankashyap4690]

heading showing useMemo but she is using React.memo()

[@kundandewangan]

Yes absolutely right both are different

Mam actually jab apne dusre button par count={count} child component pass karne ke liye, pass karha tha bina koi dependency ke data fer bhi console per a raha tha actually we should try this yeh correct hai apke wala me data console per a raha tha try karna Please pinned Message for acknowledge

[@ayushsinghteotia7240]

Hello I have one question jab aapne or ek function banya count ka to jab callback empty tha [ ] to bss humara first addition re render nhi hora tha ryt and otherside count increase hora tha re render hora tha even jab humne ye bhi mention nhi Kiya the [count] so i am confused if i add this[ add] so both are re rendering i hope u will reply :)

[@mohammedsohail9529]

12:08 while using callback fn you have written count in an empty array so that you can access the child component is it? Because without writing count in that array I could still print child component. Why is it?

[@sarfrazansari6900]

very easy way of explanation keep doing good work.

[@tech-no-logy-y1w]

❤Thank you mem wonderful explanation but I have a doubt why childA compo rendering while it's not mentioned in empty dependency in learning usecallback can you explain it or anybody guys.

[@kforcode]

function in childA component is still wrapped in the useMemo hook. is it necessary to wrap it in the useMemo hook to use the useCallback hook?

[@birenchetry5531]

Mam can we use useEffect instead callback

[@Business_Tips_Tricks786]

Good work ❤

[@YogeshkumarPatil]

React Hook useCallback has an unnecessary dependency: 'count'. Either exclude it or remove the dependency array react-hooks/exhaustive-deps ----When i put count as a dependency in the array of useCallback. why so

[@nilmandal1151]

aapke video dekhkr samjmei aya usecallback ... last sare interview mei galat ans diya mein to 😂😂😂😂😂😂

[@withexperience1569]

Awsome Explained

[@blackmamba3984]

1:01 to just 30 sec----- if usememo nad usecallback function are increses the performance so why usecallback is neeeded?? 3:44 4:53---how componenent rerendered when button is clicked this is a problem of performance 4:55 to 5:50---one solution is usememo to avoid the rerender function in the componenet that is ok but where we use useCallback hook ???? 5:56 to end where to use usecallback hook
