循环抛出带有点分名称的对象中的对象，并过滤属性Javascript

function filterNestedObject(obj, filter) {
  let result = {};

  for (let key in obj) {
    if (obj.hasOwnProperty(key)) {
      if (typeof obj[key] === 'object' && obj[key] !== null) {
        let nestedResult = filterNestedObject(obj[key], filter);
        if (Object.keys(nestedResult).length > 0) {
          result[key] = nestedResult;
        }
      } else if (filter(key, obj[key])) {
        result[key] = obj[key];
      }
    }
  }

  return result;
}

// 示例用法
let data = {
  name: 'John',
  age: 30,
  address: {
    street: '123 Main St',
    city: 'New York',
    country: 'USA'
  },
  hobbies: ['reading', 'music'],
  education: {
    degree: 'Bachelor',
    school: 'ABC University',
    graduationYear: 2020
  }
};

function filterFunc(key, value) {
  return key.includes('.');
}

let filteredData = filterNestedObject(data, filterFunc);
console.log(filteredData);
