What collections extension function can I use if I want to get first element from the list and if list is empty, then run a function that creates an element and returns it?
The closest I found is ifEmpty{} , but it returns the entire collection if it is not empty, while I don’t need the collection and just it’s first element.

list.getOrElse(0){ call function }

Looks like it is what I need. Thanks!
