## Overview

@helpers4 is a tree-shakable TypeScript utility library, not a single application pipeline: a developer imports an individual helper or category, supplies values, and receives a transformed value, comparison, or runtime utility. The graph groups the README’s major capabilities into cohesive domains and shows selected internal calls evidenced by sampled source. Most helpers are independent; the excerpts do not establish wiring between category siblings, so those links are omitted. Observable helpers have an optional RxJS peer integration.

Main entry points: [`helpers/object`](https://github.com/helpers4/typescript/tree/main/helpers/object) (Object helpers), [`helpers/guard`](https://github.com/helpers4/typescript/tree/main/helpers/guard) (Runtime guards), [`helpers/function`](https://github.com/helpers4/typescript/tree/main/helpers/function) (Function helpers), [`helpers/observable`](https://github.com/helpers4/typescript/tree/main/helpers/observable) (Observable helpers)
