Hi, I know that there are names for specific functions, like a function with an argument that returns a Boolean is a Predicate, but is there a name for a function that has an argument of type T and returns the same type ?

Like this typealias IDK<T> = (value: T) -> T

In Java, this is called a UnaryOperator : https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/util/function/UnaryOperator.html
