What are some practical examples of higher-kinded types?

Higher-kinded types are types that take other types as parameters. A common example is the 'Functor' type class in Haskell.

Can you explain how Functor works with an example?

Sure! A Functor allows you to apply a function to a wrapped value. For instance, if you have a list, you can use 'map' to apply a function to each element.

Are there other examples besides Functor?

Yes, another example is 'Monad', which represents computations as a series of steps. It allows for chaining operations.

How do Monads differ from Functors?

Monads provide a way to sequence operations, while Functors only allow you to apply a function to a value. Monads have additional structure.
