如何正确地迭代和解析javascript中的嵌套对象

function iterateNestedObject(obj, indent = 0) {
  for (let key in obj) {
    if (obj.hasOwnProperty(key)) {
      let value = obj[key];
      if (typeof value === 'object') {
        console.log(`${' '.repeat(indent)}${key}:`);
        iterateNestedObject(value, indent + 2);
      } else {
        console.log(`${' '.repeat(indent)}${key}: ${value}`);
      }
    }
  }
}

// 示例对象
let nestedObject = {
  name: 'John',
  age: 30,
  address: {
    street: '123 Main St',
    city: 'New York',
    country: 'USA'
  }
};

// 调用递归函数
iterateNestedObject(nestedObject);

name: John
age: 30
address:
  street: 123 Main St
  city: New York
  country: USA
