Question

import moment from 'moment';
import CalendarPicker from 'react-native-calendar-picker';

const ChechAvailability = () => {

    const [date, setDate] = useState([]);
    const [userDate, setUserDate] = useState('');

    const navigation = useNavigation();

    axios.post("http://192.168.0.19:3000/booked_dates").then((resp) => {
          setDate(resp.data)
        });

    useEffect(() => {
        setDate(date);
    }, [date]);

    // console.log(date);

    const listItems = date.map((items) => moment(items.booking_date).format('YYYY-MM-DD'));
    // console.log(listItems);


    let today = moment();
    let day = today.clone().startOf('month');
