迭代react中的对象内部的对象

function iterateObject(obj) {
  Object.keys(obj).forEach(key => {
    if (typeof obj[key] === 'object') {
      iterateObject(obj[key]);
    } else {
      console.log(key, obj[key]);
    }
  });
}

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

iterateObject(data);
