IO Monad

The IO Monad is a concept from programming that helps manage side effects—actions like reading user input or writing to a screen—that aren't pure computations. It acts as a container for these effects, allowing them to be composed and controlled in a predictable way. By encapsulating side effects, the IO Monad ensures that programs remain modular, testable, and maintainable, while still performing necessary real-world interactions. Essentially, it provides a structured approach to handle actions that interact with the outside world, integrating them seamlessly into functional programming paradigms.
