代码如下:

/**
 * @description 判断currentDate是否在timeQuantum区间内
 * @param {String} currentDate 当前时间(比较的时间), 例: '2023-03-30 00:00:00'
 * @param {Array} timeQuantum 时间段, 例: ['2023-03-30 00:00:00', '2023-04-30 00:00:00']
 * @returns {Boolean} true在时间段内, false不在时间段内
 * @example let isTrue = isTimeWithin('2023-03-30 00:00:00', ['2023-03-30 00:00:00', '2023-04-30 00:00:00'])
 */

function isTimeWithin(currentDate, timeQuantum) {
  let isBetween = true;
  let currentTime = new Date(currentDate);
  let startTime = new Date(timeQuantum[0]);
  let endTime = new Date(timeQuantum[1]);
  let t1 = currentTime.getTime() - startTime.getTime();
  let t2 = currentTime.getTime() - endTime.getTime();
  if (t1 < 0 || t2 > 0) {
    isBetween = false;
  } 
  return isBetween;
}

console.log(isTimeWithin('2023-03-30 00:00:00', ['2023-03-30 00:00:00', '2023-04-30 00:00:00'])); /* true */
console.log(isTimeWithin('2023-03-20 00:00:00', ['2023-03-30 00:00:00', '2023-04-30 00:00:00'])); /* false */
