不同js之间如果传递参数

// 位置参数
function greet(firstName, lastName) {
    console.log(`Hello, ${firstName} ${lastName}!`);
}
greet('John', 'Doe'); // 输出: Hello, John Doe!

// 默认参数
function greetWithDefault(firstName = 'Guest', lastName = '') {
    console.log(`Hello, ${firstName} ${lastName}!`);
}
greetWithDefault(); // 输出: Hello, Guest !

// 剩余参数
function sum(...numbers) {
    return numbers.reduce((acc, num) => acc + num, 0);
}
console.log(sum(1, 2, 3, 4)); // 输出: 10

// 解构赋值
function printUser({ name, age }) {
    console.log(`Name: ${name}, Age: ${age}`);
}
printUser({ name: 'Alice', age: 30 }); // 输出: Name: Alice, Age: 30

function add(a, b) {
    if (typeof a !== 'number' || typeof b !== 'number') {
        throw new Error('Both arguments must be numbers');
    }
    return a + b;
}

function multiply(multiplier, ...args) {
    return args.map(arg => arg * multiplier);
}
console.log(multiply(2, 1, 2, 3)); // 输出: [2, 4, 6]
