以下是练习题

console.log(1);
setTimeout(function () {
  console.log(2);
  let promise = new Promise(function (resolve, reject) {
    console.log(3);
    resolve();
  }).then(function () {
    console.log(4);
  });
}, 1000);
setTimeout(function () {
  console.log(5);
  let promise = new Promise(function (resolve, reject) {
    console.log(6);
    resolve();
  }).then(function () {
    console.log(7);
  });
}, 0);
let promise = new Promise(function (resolve, reject) {
  console.log(8);
  resolve()
}).then(function () {
  console.log(9);
}).then(function () {
  console.log(10)
});
console.log(11);
//执行顺序：1 8 11 9 10 5 6 7 2 3 4
