Monio is a JavaScript library providing an async-capable IO monad (including 'do' style) along with companion monads like Maybe, Either, and observable variants. It aims to bring powerful functional programming abstractions to JS with a rich, well-documented implementation.

Use cases

• handle side effects functionally in JavaScript with an IO monad
• compose async operations without promise chaining
• use Maybe and Either monads for null and error handling
• write do-notation style functional code in JS
• learn functional programming and monads in JavaScript
• manage observable/reactive streams with monadic composition

When to choose

• you want a mature, feature-rich IO monad implementation for JavaScript
• you're doing functional programming in JS and need Maybe/Either/IO monads
• you need async-aware monadic composition with do-style syntax
• you want a library with extensive documentation and tutorials on monads

When to avoid

• your team is unfamiliar with functional programming concepts
• you need a minimal zero-dependency utility rather than a full FP toolkit
• you're working in a non-JavaScript environment
