What is genericity?

Genericity refers to the property of being generic, or applicable to a wide range of cases or instances. In programming languages, genericity allows programmers to write code that can function with different types of data without having to write separate code for each type. This is often achieved through the use of generic data types, such as templates in C++ or generics in Java. Genericity also has applications in mathematics, where it is used to describe properties or behaviors that hold for most or all members of a particular set or category. For example, a generic property of all triangles might be that their internal angles add up to 180 degrees.
