I guess you could keep it that way, or do
`if(firstName?.isNotEmpty == true)`

Or you could add an extension such as

```fun String?.isNotNullOrEmpty(): Boolean {
    return !this.isNullOrEmpty()
}```
If you just want it to be more verbose

You could just put each component in a list and then filter/map over it

so something like:
```val parts = listOf(firstName, middleInitial, lastName)
return parts
   .filter { it.isNotBlank() }
   .map { it.trim() }
   .joinToString(" ")```


How about the testing part? Because I don’t have `else {}` jacoco complains about missing cases.

If I go the filter/map approach, need to see if that improved coverage
