How to destructure object properties with key names that are invalid variable names?

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": []

Destructuring does not work in this case because
is not a valid variable name.

const { key-with-dash } = object;

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

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

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

console.log("foo", foo);
