从JS配置对象中提取数据以创建新对象

const config = {
  name: 'John Doe',
  age: 30,
  email: 'johndoe@example.com',
  address: {
    street: '123 Main St',
    city: 'New York',
    country: 'USA'
  }
};

const { name, age, email } = config;
const { street, city, country } = config.address;

const extractedData = Object.assign({}, config);

const extractedData = {};
extractedData.name = config.name;
extractedData.age = config.age;
extractedData.email = config.email;
extractedData.address = {};
extractedData.address.street = config.address.street;
extractedData.address.city = config.address.city;
extractedData.address.country = config.address.country;
