## What it is
A set of tiny, composable React components for handling state via render props. It provides typed value helpers (Boolean, Number, Array, Map, etc.) exposing transforms like toggle, increment, and filter to build stateful UI primitives.

## Use cases
- manage toggle state in react without rewriting boolean logic
- build a counter component with increment and decrement
- handle array state like push and filter in react components
- create headless dropdowns popovers and tooltips
- avoid reimplementing state management logic for common value types

## When to choose
- you use render props and want tiny composable state helpers
- you keep rewriting toggle, increment, or array mutation logic
- you want headless, unstyled state primitives for custom UIs

## When to avoid
- you use modern React hooks, which cover most of these cases
- you need a maintained library - the latest release is from 2019
- you prefer a full state management solution like Redux or Zustand

## Facets
- artifact type: library
- maturity: maintenance
- function: state-management, ui-components
- domain: frontend, web-development, developer-tools
- platform: browser, cross-platform
- tags: react, render-props, headless-components, javascript, nodejs
