Features

Goals

This package was designed with the following goals in mind:

1. Minimal Footprint: Keep the package size as small as possible.
2. Feature-Rich, Yet Minimal: Include essential features and paradigms from functional programming to improve readability and maintainability, while avoiding unnecessary complexity.
3. Extensibility: Allow users to create their own types based on provided foundational types.

Foundational Types

Type	Derived By	Core Purpose	Implemented
SumType<T>	Maybe<T>, Either<E, T>	A generalized base type for algebraic sum types, representing one of multiple possible values.	✅
ProductType<A, B>	Tuple	Represents a composite type that combines multiple values of different types.	❌
Functor<T>	Maybe<T>, Either<E, T>	Provides a way to apply functions to wrapped values inside a data structure.	❌
Applicative<T>	Maybe<T>, Either<E, T>	Extends Functor to allow applying functions inside a functor to values inside another functor.	❌
Monad<T>	Maybe<T>, Either<E, T>	Extends Applicative to support chaining of computations that return wrapped values.	❌
Foldable<T>	Maybe<T>	Allows folding values inside a data structure into a single result.	❌

Built-in Types

Type	Derived From	Purpose	Implemented
Maybe<T>	SumType<T>	Represents an optional value (Just or Nothing).	✅
Either<E, T>	SumType<T>	Represents a value that is either a success (Right) or an error (Left).	✅
Tuple<A, B>	ProductType<A, B>	A tuple containing two values of different types.	❌
