In this case you can utilize a single step by setting a default value for
```otherData```

```let {firstName, lastName, otherData = "otherData"} = user.profile;```

To create individual variables and an object on the same line you can set the default value of ```obj``` to previously destructured values within target

```let {firstName, lastName, obj = {firstName, lastName, otherData: "other data"}} = user.profile;```

The proposed syntax would eliminate duplicate code in the described context.
