Javascript es6将两个静态类合并为一个对象

class StaticClass1 {
  static staticMethod1() {
    console.log('This is static method 1');
  }

  static staticProperty1 = 'Static property 1';
}

class StaticClass2 {
  static staticMethod2() {
    console.log('This is static method 2');
  }

  static staticProperty2 = 'Static property 2';
}

class MergedClass extends StaticClass1, StaticClass2 {
  // 可以在这里定义新的静态方法和属性
}

// 调用合并后的静态方法和访问合并后的静态属性
MergedClass.staticMethod1(); // 输出：This is static method 1
MergedClass.staticMethod2(); // 输出：This is static method 2
console.log(MergedClass.staticProperty1); // 输出：Static property 1
console.log(MergedClass.staticProperty2); // 输出：Static property 2
