What are the different types of errors in Haskell?

In Haskell, errors can be categorized into several types: runtime errors, compile-time errors, and logical errors. Runtime errors occur during program execution, compile-time errors are detected by the compiler, and logical errors are mistakes in the program's logic.

Can you give examples of each type?

Sure! A runtime error example is trying to access an element from an empty list. A compile-time error might be a type mismatch, like trying to add a number to a string. A logical error could be an incorrect algorithm that produces the wrong output.

How can I handle these errors in my Haskell code?

You can handle errors in Haskell using techniques like pattern matching, the Maybe type for optional values, and the Either type for error handling. Additionally, using libraries like Control.Exception can help manage exceptions.

What is the Maybe type?

The Maybe type in Haskell is used to represent a value that may or may not exist. It can be either Just value if there is a value, or Nothing if there isn't. This helps in safely handling cases where a value might be absent.
