What is a Functor in Haskell?
An example of an AI chatbot conversation about Haskell's Functor concept.
What is a Functor in Haskell?
A Functor in Haskell is a type class that allows you to apply a function over wrapped values, like lists or Maybe types.
Can you give me an example of a Functor in action?
Sure! For instance, if you have a list [1, 2, 3] and you want to add 1 to each element, you can use fmap (+1) [1, 2, 3], which results in [2, 3, 4].
What is the purpose of using Functors?
Functors help in abstracting the application of functions over data structures, making code more modular and reusable.
Are there other types of Functors in Haskell?
Yes, there are several types of Functors, including Maybe, Either, and lists, each allowing different kinds of operations on wrapped values.
