How to get the value of date parameter to compare it with today date from a object of values taken from backend as a object in react useEffect?

Question

I took data from backend and I want to take one value from that data object and do calculations using that value.

const[scheduleData,setScheduleData] = React.useState();
    


    useEffect(() => {
        api.get('api/schedule')
        .then((res) => {
          //  console.log(res.data);
            setScheduleData(res.data.data);
           console.log(res.data.data.data);
        })
        .catch((err) =>{
           // console.log("error")
        })
    })

There is a value called date is in this data object. I want to take that value and compare it with today and want to print whether is it expired or not.
