如何使用无效变量名称的键名称来重构对象属性？ [英] How to destructure object properties with key names that are invalid variable names?

问题描述

由于对象键是字符串，它们可以包含任何类型的字符和特殊字符。我最近偶然发现了一个API调用接收到的对象。这个对象的关键字是' - '。

As object keys are strings they can contain any kind of characters and special characters. I recently stumbled upon an object which I receive from an API call. This object has '-' in it's key names.

const object = {
   "key-with-dash": []
}

在这种情况下，结构不起作用，因为 key-with-dash 不是有效的变量名。

Destructuring does not work in this case because key-with-dash is not a valid variable name.

const { key-with-dash } = object;

所以有一个问题来了。在这种情况下，我应该如何破坏对象？是否有可能？

So one question came to my mind. How am I supposed to destructure the object in such cases? Is it even possible at all?

推荐答案

const data = {
   "key-with-dash": ["BAZ"]
}

const {"key-with-dash": foo} = data;

console.log("foo", foo);
