How do I remove the delay the countdown timer?-CodePudding

I have made a countdown timer but every time the site is loaded, the timer takes 1.5s to load in from the default 0 values. Is there any way to preload it or make it appear instantly?

function Timer() {
  const [days, setDays] = useState(0);
  const [hours, setHours] = useState(0);
  const [minutes, setMinutes] = useState(0);
  const [seconds, setSeconds] = useState(0);

  const deadline = "February, 17, 2023";

  const getTime = () => {
    const time = Date.parse(deadline) - Date.now();

    setDays(Math.floor(time / (1000 * 60 * 60 * 24)));
    setHours(Math.floor((time / (1000 * 60 * 60)) % 24));
    setMinutes(Math.floor((time / 1000 / 60) % 60));
    setSeconds(Math.floor((time / 1000) % 60));
  };

  useEffect(() => {
    const interval = setInterval(() => getTime(deadline), 1000);

    return () => clearInterval(interval);
  }, []);

CodePudding user response：

It's because the first time you evaluate the timer is after the initial 1s delay. The easiest fix would be to call getTime before creating the interval:

useEffect(() => {
  // This will run after the component mounts
  getTime();

  // This will then run every second afterwards
  const interval = setInterval(() => getTime(), 1000);
  return () => clearInterval(interval);
}, []);
