const Timer = (props:any) => {
    const {initialMinute = 0,initialSeconds = 0} = props;
    const [ minutes, setMinutes ] = useState(initialMinute);
    const [seconds, setSeconds ] =  useState(initialSeconds);
    useEffect(()=>{
    let myInterval = setInterval(() => {
            if (seconds > 0) {
                setSeconds(seconds - 1);
            }
            if (seconds === 0) {
                if (minutes === 0) {
                    clearInterval(myInterval)
                } else {
                    setMinutes(minutes - 1);
                    setSeconds(59);
                }

        <div>
        { minutes === 0 && seconds === 0
            ? null
            : <h1> {minutes}:{seconds < 10 ?  `0${seconds}` : seconds}</h1>
