export default {}
 
interface IPersonInfo {
  name: string;
  age: number;
  sex?: string;
  show(): void;
}
 
interface IMusic {
  music: string
}

  age: number = 32;
  music: string = "雪落下的声音";
  show(): void {
    console.log(`${this.name}是延禧攻略的主演，她今年${this.age}岁了`);
    console.log(`${this.name}唱了一首歌叫${this.music}`);
    
  }
}
 
let p = new Person();
p.show();
// p.name = "周冬雨";
// p.sex = "女";
 
 
interface ITest extends Person {
  salary: number;
}
