if I have an `Array<String>?` and a `String?...

if I have an Array<String>? and a String? and I need to merge the two and return Array<String>? - is there a better way than to have a bunch of if-else checking for null (if both are null it should return null also)?

str?.let { array?.plus(it) ?: arrayOf(it) }

what if str == null but arr != null

[Marat Akhin]

Good point, then it becomes even longer:

str?.let { array?.plus(it) ?: arrayOf(it) } ?: array

and probably should be hidden as an extension function

yea it becomes hard to read, maybe a bunch of if-else isn’t too bad after all
