Can you explain what the Haskell Either type is?
The Either type in Haskell is a way to represent a value that can be one of two types. It's often used for error handling.
How do you use the Either type in a function?
You can use Either in a function to return a value or an error. For example, Either String Int
can return an error message or an integer.
Can you give me an example of a function using Either?
Sure! Here's a simple example: safeDivide :: Int -> Int -> Either String Int
which returns an error message if dividing by zero.
What are the advantages of using Either over exceptions?
Using Either allows for more explicit error handling and makes it clear when a function can fail, improving code readability.
