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`
