Point-Free

The hkt-toolbelt library introduces kind reification - transforming abstract type-level functions into concrete runtime signatures. This enables point-free programming where compositions like Pipe<[Map<Inc>, Filter<IsEven>, Reduce<Add>]> become executable functions with 1:1 corresponding types. By bridging TypeScript’s type system with runtime code, we can write type-level pipelines that are both type-safe and actually invokable.

to reify: make (something abstract) more concrete or real.

Implementing point-free (tacit) programming patterns in TypeScript using Higher Kinded Types to overcome traditional type system limitations. Point-free style eliminates explicit arguments, composing functions like pipe(map(inc), filter(isEven), reduce(add)) instead of x => x.map(inc).filter(isEven).reduce(add). Through HKT encodings, we achieve true tacit programming where type inference flows through the entire pipeline, enabling cleaner functional abstractions without sacrificing TypeScript’s type safety.
