Provides a fully-featured Option type, aka a Maybe type, with several companion helpers (parsing, LINQ). An Option type allows to represent objects that are either something (a value or a reference) or nothing. Nullable Reference Types (NRT) do not count since they are not actual .NET types but ann...

Functional programming extension for scalable JavaScript application. Defines functions such as curry, partial, etc. Also defines computation expression builder (aka monad)
A safe monadic binder that will evaluate an expression chain and return an option type with information about whether the chain succeeded or not and where it failed.
Maybe type representing optional values.
