Type Classes vs Interfaces: What's the Difference?

What are the main differences between type classes and interfaces in programming?

Type classes are a feature of languages like Haskell that allow for ad-hoc polymorphism, while interfaces are used in languages like Java to define a contract for classes.

Can you give me an example of how type classes work?

Sure! In Haskell, you might define a type class 'Eq' for types that can be compared for equality. Then, you can create instances of this class for different types like Int or String.

How do interfaces handle polymorphism?

Interfaces allow for polymorphism by enabling different classes to implement the same interface, thus providing a way to use objects of different classes interchangeably.

Which one is better to use in a project?

It depends on the programming language and the specific use case. Type classes offer more flexibility in some functional languages, while interfaces provide a clear structure in object-oriented languages.
