React: Pomodoro Clock:如何转换为` `MM:SS`？

import React, { useState, useEffect } from 'react';

function PomodoroClock() {
  const [remainingTime, setRemainingTime] = useState(1500); // 初始剩余时间为1500秒，即25分钟

  useEffect(() => {
    const timer = setInterval(() => {
      setRemainingTime(prevTime => prevTime - 1);
    }, 1000);

    return () => {
      clearInterval(timer);
    };
  }, []);

  const formatTime = (time) => {
    const minutes = Math.floor(time / 60);
    const seconds = time % 60;
    return `${String(minutes).padStart(2, '0')}:${String(seconds).padStart(2, '0')}`;
  };

  return (
    <div>
      <h1>Pomodoro Clock</h1>
      <p>Remaining Time: {formatTime(remainingTime)}</p>
    </div>
  );
}

export default PomodoroClock;
