代码语言：javascript复制
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();sleep 即等待几秒后再执行下一个逻辑
delay 即几秒之后执行具体的方法，执行结束之后，再执行下一个逻辑
