在调试器控制台中运行 es6

Question

当我在页面上打开调试器控制台时，我运行：'use strict'const userMap = new Map();userMap.set("1", {id: 200})userMap.set("2", {id: 301})userMap.set("3", {id: 102})[...userMap].sort((a, b)=> {  console.log(a[1], b[1])  return a[1] - b[1]})..我会得到一个错误：Uncaught SyntaxError: Unexpected token ...现在，当我使用丑陋的 setTimeout() 时：'use strict'const userMap = new Map();userMap.set("1", {id: 200})userMap.set("2", {id: 301})userMap.set("3", {id: 102})setTimeout(() => {    [...userMap].sort((a, b)=> {      console.log(a[1], b[1])      return a[1] - b[1]    })})现在错误不存在..我只是想知道为什么会发生这种情况？更新，这对我有用'use strict'const userMap = new Map();userMap.set("1", {id: 100});userMap.set("2", {id: 300});userMap.set("3", {id: 111});const sortBy = (sortMap, name) => {  return [...sortMap.values()].sort((a, b)=> {    return a[name] - b[name];  });};const sorted = sortBy(userMap, "id");console.log(sorted);
