How can I handle exceptions in Haskell effectively?

In Haskell, you can use the Control.Exception module for advanced exception handling. It provides functions like try, catch, and finally.

Can you explain how to use try and catch?

Sure! The try function allows you to catch exceptions in a monadic context. For example, try (readFile "file.txt") will return either the file content or an exception.

What about using finally?

The finally function ensures that a cleanup action is performed after the main action, regardless of whether an exception occurred.

Are there any best practices for exception handling in Haskell?

Yes, it's best to handle exceptions at the boundaries of your application, log them appropriately, and avoid using exceptions for control flow.
