best video i have ever seen on youtube for useMemo❤‍🔥❤‍🔥❤‍🔥❤‍🔥❤‍🔥❤‍🔥❤‍🔥

[laraibmukhtar]

No, you cannot use useMemo directly in class components because useMemo is a React hook, and hooks are designed to be used only in functional components.

What a great explanation. you cleared my concepts. Thank you very much ❤️

## difference between useEffect and useMemo
useEffect is a hook used in React for handling side effects, such as data fetching, subscribing to events, or manually manipulating the DOM. AND
useMemo is used for memoizing the result of a computation. It takes a function and a dependency list, and it returns the memoized value of that function.

[coderdhruv]

sir usememo ke jagah to useeffect bhi to use kar sakte hai, phir dono me kya difference hai...?'

[alphavibb]

Sir, Can we say without using usememo all functional component are not pure component? After using usememo hook it will become pure component?

[FSDKingSaud]

Sir according to me useMemo and useEffect hooks are same then why will we use Memo hook instead of useEffect hook ?
plaese explain it sir

[Travelmoments]

shouldComponentUpdate() use karne hoga class component me useMemo functionaly achieve karne kliye..

[bhagwattaur]

sir apne starting main bola tha ki hum function component main hook use karte hai useMemo hook hai. and class component main pure component use karte hai.

[mohanjadhav]

If observe in your past video about useEffect there also we can avoide to unwanted rerender by passing the state & props then why we need this. Or what is difference between useMemo() & useEffect(). as per example same I can achive with the useEffect() as well right ?

[syedsaad]

[rupeshdewangan]

No, because hooks are not implement in class component, please correct me if I'm wrong.
