function repeat(fn, times, delay) {
  return async function (...args) {
    for (let i = 0; i < times; i++) {
      await new Promise((resolve, reject) => {
        setTimeout(() => {
          fn.call(this, ...args)
          resolve()
        }, delay)
      })
    }
  }
}
const repeatFn = repeat(console.log, 4, 1000)
// 函数调用四次，每次间隔 1s 打印 hello
repeatFn('hello')
