📖 Big inspiration from fp-ts, @sweet-monads

👇👇👇 Modules

- Option<T> - Forget about nulls and undefined

- Result<T, E> - Handle errors like a god

- Iter<T> - Lazy iterables with superpowers

- Schema - Pseudo pattern-matching for js

👆👆👆 Everything is described within modules

Installation

npm i kirka
# or
npm i github:numfin/kirka
# or fork it and instal from your own repo

Usage described in modules readme. All documentation inside JSDoc (autocomplete)

Why not fp-ts?

1. I tried fp-ts
2. I realised they have terrible documentation.
3. Using things required reading ton of types and remembering everything.
4. My friend suggested trying sweet-monads.

Why not sweet-monads

• No documentation
• Not a lot of functionality (e.g. conversions between types)
• Typing looks weak (tons of overloads without reason)
• Lack of esm support
• Class context complexity
