useCallback vs useEffect

[highmountaindev109]

I'd like to know the difference between useCallback vs useEffect and how to use them

Hi, @highmountaindev109. Good question
The main difference between useCallback and useEffect is that useCallback is used to memoize a function instance, while useEffect is used to manage side effects.

useEffect(() => {
// execute when state changed
() => {
// execute before state is changed
}
}, [state]);

const myFunction = useCallback(() => {
// execute your logic for myFunction
}, [state]);

It looks great! @whitehorse21 It would be great if you could add a code snippet in a format like that,

const myFunction = useCallback(() => {
// execute your logic for myFunction
}, [state]);
