如何验证TypeScript中的参数数量

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

// 调用示例
console.log(greet("Alice", 30)); // 正确
// console.log(greet("Bob")); // 错误：缺少参数 'age'

function greetOptional(name: string, age?: number): string {
    if (age !== undefined) {
        return `Hello, ${name}! You are ${age} years old.`;
    } else {
        return `Hello, ${name}!`;
    }
}

// 调用示例
console.log(greetOptional("Alice")); // 正确
console.log(greetOptional("Bob", 25)); // 正确

function greetMultiple(...names: string[]): string {
    return `Hello, ${names.join(", ")}!`;
}

// 调用示例
console.log(greetMultiple("Alice", "Bob")); // 正确
console.log(greetMultiple("Charlie")); // 正确

function greetOverload(name: string): string;
function greetOverload(name: string, age: number): string;
function greetOverload(name: string, age?: number): string {
    if (age !== undefined) {
        return `Hello, ${name}! You are ${age} years old.`;
    } else {
        return `Hello, ${name}!`;
    }
}

// 调用示例
console.log(greetOverload("Alice")); // 正确
console.log(greetOverload("Bob", 30)); // 正确
// console.log(greetOverload(123)); // 错误：参数类型不匹配
