从嵌套数组中获取object中值的路径

function findValuePath(arr, target) {
  // 定义一个辅助函数来递归遍历数组和对象
  function traverse(obj, path) {
    for (let key in obj) {
      if (obj[key] === target) {
        // 找到目标值，返回路径
        path.push(key);
        return path;
      } else if (typeof obj[key] === 'object') {
        // 继续递归遍历嵌套的数组和对象
        let result = traverse(obj[key], path.concat(key));
        if (result) {
          return result;
        }
      }
    }
    return null; // 没有找到目标值
  }

  return traverse(arr, []);
}

const nestedArray = [
  {
    name: 'Alice',
    age: 25,
    address: {
      city: 'New York',
      country: 'USA'
    }
  },
  {
    name: 'Bob',
    age: 30,
    address: {
      city: 'London',
      country: 'UK'
    }
  }
];

const targetValue = 'UK';
const path = findValuePath(nestedArray, targetValue);

console.log(path); // 输出: ["1", "address", "country"]
