如何从数组中找到最接近的值？

function findClosestValue(target, array) {
  let minDiff = Infinity;
  let closestValue;

  for (let i = 0; i < array.length; i++) {
    const diff = Math.abs(array[i] - target);
    if (diff < minDiff) {
      minDiff = diff;
      closestValue = array[i];
    }
  }

  return closestValue;
}

const targetValue = 10;
const array = [5, 8, 12, 15, 20];

const closestValue = findClosestValue(targetValue, array);
console.log("最接近的值为：" + closestValue);
