In programming it means that. the function can be applied to arguments of many types, or WebThe concept of type classes is actually introduced in Haskell. This is used to implement ad-hoc polymorphism. In Scala there is no special feature called type class like Haskell, but as we know scala is a combination of functional and object-oriented so we can implement type classes via scala inbuilt features like type parameterization or generics. crystal michelle turner https://gizardman.com
