purify

Master the Purify library for practical functional programming in TypeScript with algebraic data types (Maybe, Either, EitherAsync, MaybeAsync), composable error handling, data transformations, Codec for runtime type safety, List operations, Tuple utilities, and functional patterns. Use when working with Purify's Maybe/Either types, async error handling with EitherAsync/MaybeAsync, runtime validation with Codecs, or building practical functional TypeScript applications with cleaner syntax than fp-ts.
