2621\. Sleep
Easy
Given a positive integer `millis`, write an asynchronous function that sleeps for `millis` milliseconds. It can resolve any value.
**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.
**Constraints:**
* `1 <= millis <= 1000`
