js中调用另一个js方法

function greet(name) {
    console.log(`Hello, ${name}!`);
}

greet('World'); // 输出: Hello, World!

const person = {
    greet: function(name) {
        console.log(`Hello, ${name}!`);
    }
};

person.greet('World'); // 输出: Hello, World!

// math.js
export function add(a, b) {
    return a + b;
}

// main.js
import { add } from './math.js';

console.log(add(2, 3)); // 输出: 5

// 异步方法示例
function fetchData(url) {
    return fetch(url)
        .then(response => {
            if (!response.ok) {
                throw new Error('Network response was not ok');
            }
            return response.json();
        });
}

fetchData('https://api.example.com/data')
    .then(data => console.log(data))
    .catch(error => console.error('Error:', error));
