What are custom types in Haskell?
Custom types in Haskell allow you to define your own data structures, enhancing type safety and code clarity.
Can you give me an example of a custom type?
Sure! Here's a simple example: data Shape = Circle Float | Rectangle Float Float defines a Shape type that can be either a Circle or a Rectangle.
How do I use pattern matching with custom types?
You can use pattern matching to deconstruct custom types. For example:
area :: Shape -> Float
area (Circle r) = pi * r * r
area (Rectangle w h) = w * h
