What are the common uses of type classes in programming?

What are the common uses of type classes in programming?

Type classes are used to define a set of functions that can operate on different types. They enable polymorphism, allowing functions to work with any type that implements the type class.

Can you give me an example of a type class?

Sure! A common example is the 'Eq' type class in Haskell, which defines equality operations. Any type that implements 'Eq' can be compared for equality.

How do type classes improve code reusability?

Type classes allow you to write generic functions that can operate on any type that implements the required interface, reducing code duplication.

Are there any downsides to using type classes?

One downside is that they can introduce complexity, making the code harder to understand for those unfamiliar with the concept.

What languages support type classes?

Languages like Haskell, Scala, and Rust support type classes, each with its own implementation and features.
