Day 13: Sleep

Given a positive integer millis, write an asynchronous function that sleeps for millis milliseconds. It can resolve any value.

async function sleep(millis) {
    
}

Example 1:
Input: millis = 100
Output: 100
Explanation: It should return a promise that resolves after 100ms.
let t = Date.now();
sleep(100).then(() => {
console.log(Date.now() - t); // 100
});

Example 2:
Input: millis = 200
Output: 200
Explanation: It should return a promise that resolves after 200ms.

async function sleep(millis) {
    return new Promise((resolve)=>{
        setTimeout(resolve, millis)
        })
}
