What are some alternative types in Haskell?
In Haskell, alternative types often refer to types like 'Maybe', 'Either', and custom data types that allow for more expressive programming.
Can you explain the 'Maybe' type?
Sure! The 'Maybe' type is used to represent a value that might be present or absent. It can be either 'Just value' or 'Nothing'.
How does 'Either' differ from 'Maybe'?
The 'Either' type is used for computations that can result in two different outcomes. It can be 'Left value' or 'Right value', often used for error handling.
Can you give an example of a custom data type?
Absolutely! You can define a custom data type like this: data Shape = Circle Float | Rectangle Float Float
to represent different shapes.
