请实现一个函数，要求能在页面请求很多时，尽可能快地按照顺序输出返回的结果。

const promiseList = [
 new Promise((resolve) => {
  setTimeout(resolve, 1000)
 }),
 new Promise((resolve) => {
  setTimeout(resolve, 2000)
 }),
 new Promise((resolve) => {
  setTimeout(resolve, 3000)
 }),
 new Promise((resolve) => {
  setTimeout(resolve, 1500)
 })
]

fn(promiseList);
