If props is missing Should memo be used?

Question

React

I have this component

import React, { Fragment, memo } from "react";

const Gurdingo = () => {
  return <Fragment>100</Fragment>;
};

export default memo(Gurdingo);

Do I need to use memo here.
or react itself understands that it is not necessary to rebuild component Gurdingo.

Answer 1

In this case, instead of re-rendering, you will always get the memorized result of the first one. In some cases, this can improve performance.

Answer 2

I already gave the correct answer here: Do I need to use useMemo in hooks?
