如何找到距离我的位置最近的数组位置，而不是在我后面

function findNearestLocation(myLocation, locationsArray) {
  let minDistance = Infinity;
  let nearestIndex = -1;

  for (let i = 0; i < locationsArray.length; i++) {
    const location = locationsArray[i];
    const distance = calculateDistance(myLocation, location);

    if (distance < minDistance) {
      minDistance = distance;
      nearestIndex = i;
    }
  }

  return nearestIndex;
}

function calculateDistance(location1, location2) {
  // 使用合适的距离计算方法计算两个位置之间的距离
  // 这里以欧氏距离为例
  const latDiff = location1.latitude - location2.latitude;
  const lngDiff = location1.longitude - location2.longitude;
  return Math.sqrt(latDiff * latDiff + lngDiff * lngDiff);
}

// 示例用法
const myLocation = {
  latitude: 40.7128,
  longitude: -74.0060
};

const locations = [
  { latitude: 40.7128, longitude: -74.0060 },
  { latitude: 34.0522, longitude: -118.2437 },
  { latitude: 51.5074, longitude: -0.1278 }
];

const nearestIndex = findNearestLocation(myLocation, locations);
console.log("最近位置的索引：" + nearestIndex);
console.log("最近位置的坐标：" + JSON.stringify(locations[nearestIndex]));
