What is the Reader Monad in Haskell?

What is the Reader Monad in Haskell?

The Reader Monad is a design pattern in Haskell that allows you to pass shared environment data implicitly through functions.

Can you give me an example of how to use the Reader Monad?

Sure! Here's a simple example: you can define a Reader that takes a configuration and returns a value based on it.

How does it differ from other monads?

Unlike other monads, the Reader Monad focuses on dependency injection, allowing functions to access shared data without explicit parameters.

What are some practical use cases for the Reader Monad?

It's often used in applications that require configuration settings, such as web applications or complex computations.
