lodash debounce in React functional component not working
Lodash debounce not working in React
看起來應該是因為 react functional component render 產生的 instance 不一樣
will be a new function for every render. You can use the useCallback hook to make sure that the same function is being persisted between renders and it will work as expected.

 // initial render register addEventListener once
    useEffect(() => {
        window.addEventListener('scroll', onScroll)
        return () => window.removeEventListener('scroll', onScroll)
    }, [])

    const onScroll = _.throttle(() => {
        setValue(value)
    }, 100)
