使用Javascript,如何确保日期范围有效？

const startDate = new Date('2022-01-01');
const endDate = new Date('2022-01-31');

function isDateInRange(date, startDate, endDate) {
  return date >= startDate && date <= endDate;
}

const dateToCheck = new Date('2022-01-15');

if (isDateInRange(dateToCheck, startDate, endDate)) {
  console.log('日期在范围内');
} else {
  console.log('日期不在范围内');
}
