在Typscript中构建丰富对象的函数的最佳方法是什么

// 定义一个接口来描述对象的属性
interface Person {
  name: string;
  age: number;
  gender: string;
}

// 定义一个类来实现接口，并创建对象
class PersonBuilder {
  private person: Person;

  constructor() {
    this.person = {} as Person;
  }

  setName(name: string): PersonBuilder {
    this.person.name = name;
    return this;
  }

  setAge(age: number): PersonBuilder {
    this.person.age = age;
    return this;
  }

  setGender(gender: string): PersonBuilder {
    this.person.gender = gender;
    return this;
  }

  build(): Person {
    return this.person;
  }
}

// 使用构建器创建对象
const person = new PersonBuilder()
  .setName("John Doe")
  .setAge(25)
  .setGender("Male")
  .build();

console.log(person);
