A JavaScript library providing Fantasy-Land compatible algebraic data types (Either, Maybe, Future, IO, Reader, State, Tuple, Identity) designed for easy integration with Ramda. The project is no longer developed and its maintainers recommend alternatives like Sanctuary, Folktale, and Fluture.

Use cases

• use Maybe and Either types for null-safe error handling in JavaScript
• integrate functional monads with Ramda pipelines
• implement functional error handling without exceptions
• model side effects with IO and Future types
• learn functional programming patterns like monads and functors in JS

When to choose

• you are already committed to a legacy codebase that depends on ramda-fantasy
• you need a minimal, well-known set of Fantasy-Land types for a small project

When to avoid

• starting a new project - use Sanctuary, Folktale, or Fluture instead
• you need actively maintained types with ongoing bug fixes and security patches
• you need types beyond the fixed set provided (e.g., Task, Validation)
