js实现 delay 和 sleep函数

console.log("====sleep===");
// sleep  等待几秒
const sleep = (seconds) =>
    new Promise((resolve) => setTimeout(resolve, seconds));
async function sleepTest() {
    console.log("start");
    await sleep(1000);
    console.log("stop");
}
sleepTest();
console.log("====delay===");
// delay  延迟几秒后执行函数
function delay(fn, seconds, ...args) {
    return new Promise((resolve) =>
        setTimeout(() => {
            // console.log(args);
            Promise.resolve(fn(...args)).then(resolve);
        }, seconds)
    );
}

async function delayTest() {
    console.log("Start");
    await delay(
        (...args) => {
            console.log("delay log", ...args);
        },
        1000,
        "aa",
        "bb",
        "cc",
        "dd"
    );
    console.log("stop");
}
delayTest();
