How do I use polymorphism in Haskell?

Polymorphism in Haskell allows functions to operate on different types. Would you like to see an example?

Yes, please provide an example of polymorphism in action.

Sure! Here's a simple example using the Num typeclass. You can define a function that works with any numeric type:

add :: Num a => a -> a -> a
add x y = x + y

This function can take integers, floats, etc.

What are typeclasses and how do they relate to polymorphism?

Typeclasses are a way to define a set of functions that can operate on different types. They enable polymorphism by allowing you to write generic functions that can work with any type that implements the typeclass.
