Type class - Wikipedia
This article is about polymorphic type systems in computer science. For the mathematical class of order-types of a given cardinality, see Glossary of set theory § T. In computer science, a type class is a type system construct that supports ad hoc polymorphism. This is achieved by adding constraints to type variables in parametrically polymorphic types. Such a constraint typically involves a type
Parametric polymorphism - Wikipedia
In programming languages and type theory, parametric polymorphism allows a single piece of code to be given a "generic" type, using variables in place of actual types, and then instantiated with particular types as needed.[1]: 340 Parametrically polymorphic functions and data types are sometimes called generic functions and generic datatypes, respectively, and they form the basis of generic progr
