Millised põhjused võimaldavad kasutada TODO direktiivi mis tahes andmetüübi või struktuuriga?

In Kotlin, the directive TODO() is a function that always throws a NotImplementedError exception. It is declared with a return type of Nothing, which means the function never returns a value and terminates execution.

Thanks to the Nothing type, TODO() can be used anywhere where any data type or structure is expected. This allows you to temporarily mark a place in the code without worrying about the specific return type. For example:

fun getUser(): User = TODO("Implement user retrieval")

val number: Int = TODO()

val list: List<String> = TODO()

Thus, TODO() serves as a useful marker for incomplete code, allowing the program to compile and indicating places that need to be finished, regardless of the data type.
