如何将JSON对象与当前类合并

class MyClass {
  constructor() {
    this.property1 = 'default value';
    this.property2 = 0;
  }
}

function mergeJSONWithClass(json, cls) {
  const instance = new cls();

  for (const key in json) {
    if (json.hasOwnProperty(key)) {
      if (instance.hasOwnProperty(key)) {
        instance[key] = json[key];
      } else {
        // 可选择忽略或添加属性到当前类
        instance[key] = json[key];
      }
    }
  }

  return instance;
}

const json = {
  property1: 'new value',
  property2: 42,
  property3: 'additional value'
};

const mergedInstance = mergeJSONWithClass(json, MyClass);
console.log(mergedInstance);
