使用JavaScript在数组中查找最接近的日期

function findClosestDate(dates, targetDate) {
  let closestDate = dates[0];
  let minDifference = Math.abs(dates[0] - targetDate);

  for (let i = 1; i< dates.length; i++) {
    const difference = Math.abs(dates[i] - targetDate);
    if (difference < minDifference) {
      closestDate = dates[i];
      minDifference = difference;
    }
  }

  return closestDate;
}

const dates = [
  new Date('2022-01-01'),
  new Date('2022-01-10'),
  new Date('2022-01-15'),
  new Date('2022-01-20')
];

const targetDate = new Date('2022-01-12');

const closestDate = findClosestDate(dates, targetDate);
console.log(closestDate); // 输出：2022-01-10
