如何在javascript中合并嵌套对象

function mergeObjects(obj1, obj2) {
  const merged = Object.assign({}, obj1); // 深拷贝obj1

  for (let key in obj2) {
    if (obj2.hasOwnProperty(key)) {
      if (typeof obj2[key] === 'object' && obj2[key] !== null && !Array.isArray(obj2[key])) {
        if (typeof merged[key] === 'object' && merged[key] !== null && !Array.isArray(merged[key])) {
          merged[key] = mergeObjects(merged[key], obj2[key]); // 递归合并嵌套对象
        } else {
          merged[key] = mergeObjects({}, obj2[key]); // 创建新对象并递归合并
        }
      } else {
        merged[key] = obj2[key]; // 合并普通属性
      }
    }
  }

  return merged;
}

const obj1 = {
  a: 1,
  b: {
    c: 2,
    d: {
      e: 3
    }
  }
};

const obj2 = {
  b: {
    d: {
      f: 4
    },
    g: 5
  },
  h: 6
};

const mergedObj = mergeObjects(obj1, obj2);
console.log(mergedObj);
