The Monad Invasion - Part 3: Railway-Oriented Programming

Railway-Oriented Programming (ROP) is a functional approach to error handling that considers the "Happy Path" as the main track, providing the expected behavior. It aims to handle errors in a way that ensures the full execution of a workflow. ROP uses Monads to create branching between tracks and can be used to replace exception-based approaches. While it has its limitations, such as requiring the same type of failure for all failures, it offers benefits like cleaner code, easier readability, and more explicit intent. By using ROP, developers can handle errors in a more elegant and maintainable way, making their code more robust and reliable.
