An example of an AI chatbot conversation about Haskell's applicative functors.
What are applicative functors in Haskell?
Applicative functors are a type class in Haskell that allow you to apply functions wrapped in a context to values wrapped in a context.
Can you give me an example of how to use them?
Sure! If you have a function f that takes two arguments and returns a value, you can use <*> to apply it to two applicative functors.
What is the difference between functors and applicative functors?
Functors allow you to apply a function to a value in a context, while applicative functors allow you to apply functions that are also in a context.
Are there any practical applications of applicative functors?
Yes, they are often used in scenarios like validating multiple inputs or combining results from different computations.
