Type class

A type class is a concept from programming, particularly in languages like Haskell, that allows developers to define a common set of operations for different data types. Think of it like a blueprint for functionality: if a type belongs to a type class, it must implement certain behaviors. This means you can write functions that work on any type that fits that class, promoting code reusability and consistency. For example, a type class might define a way to "compare" values, allowing different types to be compared as long as they follow the rules of that type class.
