返回值自动包装为Promise：即使函数内部返回的是一个普通值，这个值也会被自动包装成一个已解决的Promise。 async function foo () { return 42; // 等价于 return Promise.resolve (42) } 函数内部可以使用await关键字：await只能在async函数内部使用，它用于暂停函数的执行，等待一个Promise的解决。

3. async/await：V8 的协程调度器，远不止语法糖 3.1 async 函数的本质：一个自动生成 Promise 的状态机编译器 async 关键字并非给函数加了个“异步标签”，而是告诉 V8 引擎：“请把这个函数体，编译成一个基于 Promise 状态机的执行器”。 当你声明 async function foo () { ...
