Hi, why don't we use react.memo to prevent the rendering instead of call back the function and passing as prop in parent. At the end of thr day react.memo also doing the same. Hope you got my question.

Thank you! what is the difference between React.memo and useMemo() ? in this case of useCallBack() why exactly we need to memorise the function? and rendering means the refresh of the page? thank you!

[@DipeshMalvia]

Hi Ahmed, page refresh and page rendering are two different things. In React rendering means create react element and display it on the screen. As react element are immutable so when you make changes in DOM the component has to rerender to display the updated value. You will never notice a page refresh happens when you click on button or change the state it is just renders the updated DOM. link for reference - reactjs.org/docs/rendering-elements.html www.telerik.com/blogs/what-is-render-react-how-do-you-force-it

[@DipeshMalvia]

They both work same but used at different places. You can use useMemo inside the function component. But React.memo can be used in class component or top level of your function component.
