👉 In computer science, "superextension" refers to a type of abstract data type that extends an existing type. This allows for more flexibility and abstraction in designing complex systems or applications. In other words, it enables developers to create new classes with specific properties and behaviors that are not directly available in the original class. Superextensions can be used in various contexts such as programming languages like Python, Java, or C++, where a superclass is an abstract class that extends another class.
