I might have two type of payloads.

```
const payload = {
   "firstName":"Steven",
   "lastName":"Smith"
}

```

or

```
const payload = {
   "personalDetails": {
       "firstName":"Steven",
       "lastName":"Smith"
    }
}

```

How can I retrieve firstName from the payload during a REST API call.

```
const { firstName } = payload;  

```

The above code will work for the first payload but it won't for the second payload since `firstName` is nested inside `personalDetails`. Is there a clean of retrieving it in `ES6`?
