将函数参数定义为Typescript中的对象

interface Person {
  name: string;
  age: number;
}

function greet(person: Person): string {
  return `Hello, ${person.name}! You are ${person.age} years old.`;
}

type Person = {
  name: string;
  age: number;
};

function greet(person: Person): string {
  return `Hello, ${person.name}! You are ${person.age} years old.`;
}

interface Person {
  name: string;
  age: number;
  address?: string; // 可选属性
}

function greet(person: Person): string {
  let greeting = `Hello, ${person.name}! You are ${person.age} years old.`;
  if (person.address) {
    greeting += ` You live at ${person.address}.`;
  }
  return greeting;
}

const person1: Person = { name: "Alice", age: 30 };
const person2: Person = { name: "Bob", age: 25, address: "123 Main St" };

console.log(greet(person1)); // 输出: Hello, Alice! You are 30 years old.
console.log(greet(person2)); // 输出: Hello, Bob! You are 25 years old. You live at 123 Main St.
