如何在nodejs上对object jSON数据进行嵌套循环

function iterateNestedJSON(data) {
  for (const key in data) {
    if (typeof data[key] === 'object') {
      iterateNestedJSON(data[key]); // 递归调用
    } else {
      console.log(key, data[key]); // 处理当前层级的数据
    }
  }
}

const nestedJSON = {
  name: 'John',
  age: 30,
  address: {
    street: '123 Main St',
    city: 'New York',
    country: 'USA'
  }
};

iterateNestedJSON(nestedJSON);

function iterateNestedJSON(data) {
  const stack = [{ obj: data, prefix: '' }];

  while (stack.length > 0) {
    const { obj, prefix } = stack.pop();

    for (const key in obj) {
      const value = obj[key];

      if (typeof value === 'object') {
        stack.push({ obj: value, prefix: `${prefix}${key}.` });
      } else {
        console.log(`${prefix}${key}`, value);
      }
    }
  }
}

const nestedJSON = {
  name: 'John',
  age: 30,
  address: {
    street: '123 Main St',
    city: 'New York',
    country: 'USA'
  }
};

iterateNestedJSON(nestedJSON);
