从数组列表中查找与给定数组最接近的值的数组

function findClosestArray(arrList, targetArray) {
  let minDiff = Infinity;
  let closestArray = null;

  for (let i = 0; i < arrList.length; i++) {
    const diff = Math.abs(arrList[i] - targetArray);
    if (diff < minDiff) {
      minDiff = diff;
      closestArray = arrList[i];
    }
  }

  return closestArray;
}

const arrayLists = [1, 5, 10, 15, 20];
const target = 12;
const closest = findClosestArray(arrayLists, target);
console.log(closest); // 输出 10
