Can you explain what Haskell monads are?
Sure! Haskell monads are a design pattern used to handle side effects in functional programming. They allow for chaining operations while maintaining a functional style.
How do monads help with IO operations in Haskell?
Monads encapsulate IO actions, allowing you to sequence them while keeping the pure functional nature of Haskell. The 'IO' type represents computations that perform input/output.
Can you give me an example of using a monad for IO?
Absolutely! Here's a simple example: using the 'do' notation, you can read a line from the input and then print it. It looks like this: do { line <- getLine; putStrLn line }
.
What are some common monads used in Haskell?
Some common monads in Haskell include Maybe, List, and State, each serving different purposes like handling optional values, non-determinism, and stateful computations.
