定时器的 Promise API

timers/promises API 提供了一组可返回 Promise 对象的可供选择的定时器函数。 API 可通过 require('node:timers/promises') 访问。

import {
  setTimeout,
  setImmediate,
  setInterval,
} from 'timers/promises';const {
  setTimeout,
  setImmediate,
  setInterval,
} = require('node:timers/promises');

The timers/promises API provides an alternative set of timer functions that return Promise objects. The API is accessible via require('node:timers/promises').

import {
  setTimeout,
  setImmediate,
  setInterval,
} from 'timers/promises';const {
  setTimeout,
  setImmediate,
  setInterval,
} = require('node:timers/promises');
