When we code, we tend to focus on the “happy path”. Yet in the real world, there is validation, logging, network errors, and other “unhappy paths”.

Railway-oriented programming is an approach that makes sure we think about and handle all these possible outcomes. Some languages regularly benefit from it; now, it’s time for TypeScript.
