js 延时执行下一次循环

function delayedLoop(iterations, delay, callback) {
    let i = 0;

    function next() {
        if (i < iterations) {
            callback(i);
            i++;
            setTimeout(next, delay);
        }
    }

    next();
}

// 使用示例
delayedLoop(5, 1000, (index) => {
    console.log(`这是第 ${index + 1} 次循环`);
});

async function delayedLoop(iterations, delay) {
    for (let i = 0; i < iterations; i++) {
        // 执行循环体中的操作
        console.log(`这是第 ${i + 1} 次循环`);

        // 等待指定的延时
        await new Promise(resolve => setTimeout(resolve, delay));
    }
}

// 使用示例
delayedLoop(5, 1000);
