Mida esindab 'Nothing' kontseptsioon programmeerimise või Kotlin keele kontekstis?

In Kotlin, the Nothing type represents a type that has no values. It is used to denote functions that never return a result (for example, they always throw an exception or run infinitely).

Example:

fun fail(message: String): Nothing {
    throw IllegalStateException(message)
}

Here, the fail function is declared with the Nothing type, which means it will not terminate normally and will not return a value. This helps the compiler understand that after calling such a function, the code will not continue.
