我使用Chrome打印为
{
2 : 1,
3 : 2,
length : 4
}
分析：
1. push 方法的行为： Array.prototype.push 方法根据对象的 length 属性决定插入位置。调用 push 时，元素会被添加到索引 length 处，并将 length 加 1。
2. 第一次 push(1)： 初始 length 为 2，元素 ...

setTimeout 定时器，可以延迟执行，属于宏任务，在JavaScript事件循环中，执行优先级最低。 Promise 本身是同步的立即执行函数， 当在executor中执行resolve或者reject的时候, 此时是异步操作，
会先执行then/catch等，当主栈完成后，才会去调用resolve/reject中存放的方法执行，打印p的时候，是打印的返回结果，一个Promise实例。resolve函数的作用是，将Promise对象的状态从“未完成”变为“成功”（即从 ...
