使用嵌套键组合两个数据的NodeJS

function combineData(data1, data2) {
  let combinedData = {};

  for (let key in data1) {
    combinedData[key] = data1[key];
  }

  for (let key in data2) {
    if (combinedData.hasOwnProperty(key)) {
      if (typeof data2[key] === 'object' && typeof combinedData[key] === 'object') {
        combinedData[key] = combineData(combinedData[key], data2[key]);
      } else {
        combinedData[key] = data2[key];
      }
    } else {
      combinedData[key] = data2[key];
    }
  }

  return combinedData;
}

// 示例数据
const data1 = {
  user: {
    name: 'John',
    age: 30
  },
  preferences: {
    theme: 'dark',
    language: 'en'
  }
};

const data2 = {
  user: {
    name: 'Jane',
    email: 'jane@example.com'
  },
  preferences: {
    theme: 'light',
    timezone: 'GMT+1'
  },
  bookmarks: {
    favoriteWebsite: 'https://www.example.com',
    favoriteArticle: 'https://www.example.com/article'
  }
};

// 调用函数组合数据
const combinedData = combineData(data1, data2);
console.log(combinedData);
