在我的 Node.js 应用程序中，我使用带有 oauth2 身份验证的 googleapis 来发送电子邮件。突然，我在启动应用程序时发现了这个错误。

考虑这个“复杂”对象：

const obj = {
    nestedArray: [
        { stuff: "things" }
    ],
    nestedObj: {
        key1: "value1",
        key2: "value2"
    }
}

我正在寻找一种优雅的单行解决方案来解构key1、key2和stufffrom obj。

我当前的解决方案如下所示并且工作得很好：

const { nestedArray, nestedObj: { key1, key2 } } = obj
const { stuff } = nestedArray[0]

但我宁愿在一行中这样做：

const { array[0]: { stuff }, nestedObject: { key1, key2 } } = obj

但显然这行不通。有什么方法可以像我想要的那样在一行中完成此操作吗？还是我对 ES6 要求太高了？我非常乐意接受“不”的答案，只要它提供了一个很好的解释为什么不。
