To fix that, we should use the cloning loop that examines each value of `user[key]` and, if it's an object, then replicate its structure as well. That is called a "deep cloning".
There's a standard algorithm for deep cloning that handles the case above and more complex cases, called the [Structured cloning algorithm](https://html.spec.whatwg.org/multipage/structured-data.html#safe-passing-of-structured-data).
We can use recursion to implement it. Or, not to reinvent the wheel, take an existing implementation, for instance [_.cloneDeep(obj)](https://lodash.com/docs#cloneDeep) from the JavaScript library [lodash](https://lodash.com).
