Practical Error Handling with fp-ts

What problem does it solve?

This Skill helps developers stop throwing exceptions and instead represent failures as explicit data using fp-ts's Either and TaskEither, enabling more predictable and testable code.

Core Features & Use Cases

• Return errors as values with Either and TaskEither to model failures in synchronous and asynchronous steps.
• Chain multiple operations safely with E.chain / E.chainW and TE.chain, enabling clean, composable error handling.
• Validate inputs and optionally accumulate multiple errors using an applicative style for forms and complex validations.
