An example of an AI chatbot conversation about functors in functional programming.
What are functors in functional programming?
Functors are a type of mapping structure that allows you to apply a function to values wrapped in a context, like lists or options.
Can you give me an example of a functor?
Sure! In Haskell, the Maybe type is a functor. You can use fmap to apply a function to the value inside a Maybe.
How do functors differ from monads?
Functors allow you to apply a function to a wrapped value, while monads provide a way to chain operations and manage side effects.
Are there any practical applications of functors?
Yes! Functors are widely used in functional programming for handling data transformations, especially in libraries like React for managing state.
