[@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

[@animeshkumarjha4069]

Thankyou ma'am it was wonderful explanation. Thanks a lot

[@gauravpandey7885]

Crystal clear, Nicely explained.

[@gajanankanekar9118]

Thanks. Short and sweet explanation

[@clipdotmedia]

Your teaching way is very simple and excellent

[@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?

[@paragjain8289]

like always crystal clear😄

[@NANDJEE1]

i think the best totorial on youtube for react understanding. please keep it up...

[@dilpavittarpalsingh9088]

we can alsoe use again usememo mam instead of calback in parent comp i try it and it is working

[@rahehaq5536]

Very well & simple explained . Easy to understand as well.

[@fazalurrehman410]

Hii Mam Yoshita. I realiy appriciate you. I have understood the React hooks well by watching your React videos lecture. Your way of teaching is very good. Thank you

[@muhammadaliawan9672]

[@PraveenSuthar-hg9qw]

learning prop ko agar ham useMemo bna le phir bhi vhi same kaam karega to main diffrence kya huaa useCallback and useMemo me?

[@prathamesh_7511]

Explained in detail! Thank You so much ❤

[@shubhambhoir6559]

Appreciation is must and build more n more problem solving projects on react with redux It would be more enhancing !! :)

[@bilaljaved1900]

@Yoshita jain your tutorials are great, but little mistake here 5.25, you are wrapping Child component with React.memo not with useMemo hook

[@hashamtanveer2730]

same bro if you use it only for one time you don't need to impor

[@hashamtanveer2730]

bcz its increasing build size😊

[@mahimatolani813]

Great explanation.. Just one doubt isme aapne usecallback me jaise btaya hai count pass kia h apan ne but count likhne k bina bhi jaise hi count ki state change hotti h child component rerender hota haii. aisa add k sath ni hotaa. I didnt understand the reason behind it can you please explain

[@Shreesamormatajikakar]

What is trick to remember hooks in reactjs😊

[@basitali2962]

Thank u mam just aap ki videos usememo and use callback hook literally understand hogaya thanks

[@MeerutWala-pl8nk]

Underated channel ❤❤

[@rahulgiri6403]

lekin mam maine useMemo ka use kiya useCallback ke place par. Essi same program mai . tab bhi result same. const Navbar = () => { const [add, setAdd] = useState(0); const loop = useMemo(() => { //watch this //kooio }, []); return ( {add} setAdd(add + 1)}>Add ); }; export default Navbar;

[@kanaksinghal9748]

Shree Sitaram JI Very well, Simple beginnerfriendly explaination

[@maaznaveed-z2q]

Hi Yoshita i hope u are doing well, the way you are explaining is excellent But I want to know that we can also use useMemo also instead of useCallback so What is the big difference between usememo and use Callback

[@mongalmoy_karmakar]

Very very informative. Thanks ❤

[@rkscp7711]

I have learned lot of things to you,thank you so much 🌼🙌

[@RamManoharKoruprolu]

It's a geat vedio. Everying will say about redering.But the way u said about referntial equality is good thing.

[@shivamjhamusic]

Aap konsa extension use kar rahi h , vscode me jis se apne aap inport ho jata hn component or files

[@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.

[@Meenu_Singh12]

nice video ever...

[@samarscript5824]

11:02 Itne time se jor jor se bata raha tha suna hi nhi aapne .... well done keep make such viedos 😉

[@NatureSecrets2011]

Good work ❤

[@48-it-shivamkale94]

Thanks for such content.keep going👍

[@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?

[@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

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

[@masthanvali3286]

[@mohammedmussavir5823]

Amazing explanation

[@Yourguru9]

Perfect job mam, Thanks a lot😊

[@karankhandelwal5651]

Nice explanation , just one doubt , can we not make Learning function also using usememo with empty dependency so that it gets called only on mounting of component App.js, instead of usecallback . And let the child component use memo function. I Guess in this way also we can handle without using usecallback

[@nilmandal1151]

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

[@sarfrazansari6900]

very easy way of explanation keep doing good work.
