how to save a variable with the current data saved in an interval updating state

I am builidng a typicall stopwatch/clock app in here.

The issue: When clicking Pause Button then Split Button (which prints the elapsed time) and then start back, both the stopwatch and the printed time restart. That is because I am saving the Crono time in the handleClickSplit function. Any ideas on the best way to save that current paused time to prevent the bug?

This is the image

This is my code:

export default function Home({ enableCrono }) {
  const [cronoTime, setCronoTime] = useState({ h: 0, m: 0, s: 0, ms: 0 });
  const [printTime, setPrintTime] = useState([]);
  const [interv, setInterv] = useState();
  const [status, setStatus] = useState(0);
  // 0 => not running
  // 1 => start
  // 2 => pause
  // 3 => stop

  const start = () => {
    if (cronoTime.m === 60) {
      cronoTime.h++;
      cronoTime.m = 0;
    }
    if (cronoTime.s === 60) {
      cronoTime.m++;
      cronoTime.s = 0;
    }
    if (cronoTime.ms === 100) {
      cronoTime.s++;
      cronoTime.ms = 0;
    }
    cronoTime.ms++;
    return setCronoTime({
      ms: cronoTime.ms,
      s: cronoTime.s,
      m: cronoTime.m,
      h: cronoTime.h,
    });
  };

  const handleClickStart = () => {
    start();
    setStatus(1);
    setInterv(setInterval(start, 10));
  };
  const handleClickStop = () => {
    clearInterval(interv);
    setStatus(3);
  };
  const handleClickPause = () => {
    clearInterval(interv);
    setStatus(2);
  };

  const handleClickClear = () => {
    clearInterval(interv);
    setStatus(0);
    setCronoTime({ h: 0, m: 0, s: 0, ms: 0 });
    setPrintTime([]);
  };

  const handleClickSplit = () => {
    setPrintTime((prevtime) => [...prevtime, cronoTime]);

Answer

You’re saving in your printTime array a reference to the very same cronoTime object. Just save a new object, so that changes on cronoTime do not propagate to the object in printTime:

setPrintTime((prevtime) => [...prevtime, {...cronoTime}]);
