## What it is
Omniscient is a JavaScript library providing an abstraction over React components for fast top-down rendering using immutable data structures and cursors. It acts as memoization for stateless React components via a smart predefined shouldComponentUpdate, but is now retired since React.memo covers most of its use cases.

## Use cases
- optimize React re-renders with immutable data
- memoize stateless React components
- build UIs with unidirectional data flow
- use cursors to pass shared immutable state through component trees
- write functional-style composable React components

## When to choose
- maintaining a legacy codebase already built on Omniscient
- targeting pre-16.6 React versions where React.memo is unavailable

## When to avoid
- starting a new React project - use React.memo instead
- you need actively maintained libraries
- you don't use Immutable.js or immutable data patterns

## Facets
- artifact type: library
- maturity: abandoned
- function: frontend-framework, ui-components, state-management
- domain: web-development, frontend
- platform: browser
- tags: react, immutable-data, memoization, unidirectional-dataflow, cursors, retired, nodejs, javascript
