Difference between useState and useMemo

The title of this post might seem ridiculous. Of course useState and useMemo are different.

But in one sense, they are quite similar.

Consider this example:

const [state] = useState(() => {
return calculateSomething(input)

const memo = useMemo(() => {
return calculateSomething(input)
}, [input])
