@nomicon/types is a zero-runtime library of TypeScript utility types. it can broadly be thought of as providing three classes of types: "pure utility" types for enhancing the TypeScript type system (e.g. IsNever, IsAny, IsUnion, Satisfies), "traditional helper" types abstracting over otherwise complex operations on types (e.g. List.Reverse, DeepReadonly), and "higher-kinded" types, which operate on the type level.
