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

\n\n

 

\n

Example 1:

\n\n
\nInput: millis = 100\nOutput: 100\nExplanation: It should return a promise that resolves after 100ms.\nlet t = Date.now();\nsleep(100).then(() => {\n  console.log(Date.now() - t); // 100\n});\n
\n\n

Example 2:

\n\n
\nInput: millis = 200\nOutput: 200\nExplanation: It should return a promise that resolves after 200ms.\n

请你编写一个异步函数，它接收一个正整数参数 millis ，并休眠 millis 毫秒。要求此函数可以解析任何值。

\n\n

示例 1：

\n\n
\n输入：millis = 100\n输出：100\n解释：\n在 100ms 后此异步函数执行完时返回一个 Promise 对象\nlet t = Date.now();\nsleep(100).then(() => {\n  console.log(Date.now() - t); // 100\n});\n
\n\n

示例 2：

\n\n
\n输入：millis = 200\n输出：200\n解释：在 200ms 后函数执行完时返回一个 Promise 对象\n
