React eslint error：Component definition is missing display name - reactjs

Question

Using Reac.memo to wrap my functional component, and it can run smoothly, but the eslint always reminded me two errors:
error Component definition is missing display name react/display-name
error 'time' is missing in props validation react/prop-types
Here is my code:
type Data = {
time: number;
};
const Child: React.FC<Data> = React.memo(({ time }) => {
console.log('child render...');
const newTime: string = useMemo(() => {
return changeTime(time);
}, [time]);
return (
<>
<p>Time is {newTime}</p>
{/* <p>Random is: {children}</p> */}
</>
);
});
My whole code:
import React, { useState, useMemo } from 'react';
const Father = () => {
const [time, setTime] = useState(0);
const [random, setRandom] = useState(0);
return (
<>
<button type="button" onClick={() => setTime(new Date().getTime())}>
getCurrTime
</button>
<button type="button" onClick={() => setRandom(Math.random())}>
getCurrRandom
</button>
<Child time={time} />
</>
);
};
function changeTime(time: number): string {
console.log('changeTime excuted...');
return new Date(time).toISOString();
}
type Data = {
time: number;
};
const Child: React.FC<Data> = React.memo(({ time }) => {
console.log('child render...');
const newTime: string = useMemo(() => {
return changeTime(time);
}, [time]);
return (
<>
<p>Time is {newTime}</p>
{/* <p>Random is: {children}</p> */}
</>
);
});
export default Father;

Answer 1

It's because you have eslint config which requries you to add displayName and propTypes
Do something like
const Child: React.FC<Data> = React.memo(({ time }) => {
console.log('child render...');
const newTime: string = useMemo(() => {
return changeTime(time);
}, [time]);
return (
<>
<p>Time is {newTime}</p>
{/* <p>Random is: {children}</p> */}
</>
);
});
Child.propTypes = {
time: PropTypes.isRequired
}
Child.displayName = 'Child';

If you are working with React and TypeScript, you can turn off the react/prop-types rule.
This is because TypeScript interfaces/props are good enough to replace React's prop types.
