An example of an AI chatbot conversation about Haskell type classes.
What are type classes in Haskell?
Type classes in Haskell are a way to define a set of functions that can operate on different types. They allow for polymorphism, enabling you to write more generic and reusable code.
Can you give me an example of a type class?
Sure! A common example is the 'Eq' type class, which defines equality. Any type that implements 'Eq' must provide an implementation for the '==' and '/=' operators.
How do I create my own type class?
To create your own type class, use the 'class' keyword followed by the class name and the type variables. Then, define the functions that types must implement.
What are some common type classes in Haskell?
Some common type classes include 'Ord' for ordering, 'Show' for converting to strings, and 'Num' for numeric types.
