从对象数组中查找到给定日期的最近日期

function findNearestDate(objArray, givenDate) {
  let nearestDate = null;
  let minDiff = Infinity;

  for (let i = 0; i < objArray.length; i++) {
    const currentDate = new Date(objArray[i].date);
    const diff = Math.abs(currentDate - givenDate);

    if (diff < minDiff) {
      minDiff = diff;
      nearestDate = currentDate;
    }
  }

  return nearestDate;
}

// 示例用法
const objArray = [
  { date: '2022-01-01' },
  { date: '2022-02-01' },
  { date: '2022-03-01' },
];

const givenDate = new Date('2022-02-15');
const nearestDate = findNearestDate(objArray, givenDate);

console.log(nearestDate); // 输出：2022-02-01
