将带有getter和带下划线的私有属性的Typescript类转换为Object

class MyClass {
  private _name: string;
  private _age: number;

  constructor(name: string, age: number) {
    this._name = name;
    this._age = age;
  }

  get name(): string {
    return this._name;
  }

  get age(): number {
    return this._age;
  }
}

class MyClass {
  // ...

  toObject(): object {
    return Object.assign({}, this);
  }
}

const myObj = new MyClass("John", 25);
const myObjAsObject = myObj.toObject();
console.log(myObjAsObject);

{ _name: 'John', _age: 25 }
