回滚操作： 0.查看提交的日志[非必要] 1.找到要回滚的节点id，执行 2.把回滚的代码强制推到远程分支

```js const PENDING = 'pending' const FUFILLED = 'fulfilled' const REJECTED = 'rejected' class MyPro

```js const PENDING = 'pending' const FUFILLED = 'fulfilled' const REJECTED = 'rejected' class MyPro

```js // resolve方法的实现 // 原Promise.resolva()演示 function p1() { return new Promise((resolve, reject) =

```js // PromiseAll方法模拟 // 原PromiseAll演示 function p1 () { return new Promise((resolve, reject) => {

```js // then方法参数变成可选参数 // 原promise演示 var promise = new Promise((resolve, reject) => { resolve(100)

```js // 错误捕获 const PENDING = 'pending' const FUFILLED = 'fulfilled' const REJECTED = 'rejected' cla

```js // promise的循环调用 // 错误示例 // const promise = new Promise((resolve, reject) => { // resolve(100)

```js // then链式调用 成功回调的返回值为promise对象时 const PENDING = 'pending' const FUFILLED = 'fulfilled' const R
