Typescript接口不检查方法参数吗？

interface Person {
  name: string;
  age: number;
  sayHello(message: string): void;
}

const person: Person = {
  name: "Alice",
  age: 25,
  sayHello(message: string) {
    console.log(`${this.name} says: ${message}`);
  }
};

const person: Person = {
  name: "Alice",
  age: 25,
  sayHello(message: number) { // 参数类型错误，应该是string类型
    console.log(`${this.name} says: ${message}`);
  }
};

interface SayHello {
  (message: string): void;
}

const person: Person = {
  name: "Alice",
  age: 25,
  sayHello: function(message: string) {
    console.log(`${this.name} says: ${message}`);
  }
};
