Created by: wendux

Describe the bug

import React, {useState} from 'react';

function Example(props) {
    return <div>{props.title}</div>
}

const ExampleNew = React.memo(Example, (prevProps, nextProps) => {
    // update here ，hot reload doesn't work unless refreshing the page in browser
    // console.log("2")
    console.log("1")
    return false
})


function App() {
    const [count, setCount] = useState(0);

    return (
        <div>
            <ExampleNew title={count}/>
            <button onClick={() => setCount(count + 1)}>
                Click me
            </button>
        </div>
    );
}

export default App;
