## What it is
A ~500-line JavaScript library implementing the basic virtual DOM algorithm: creating virtual trees, diffing them, and patching the real DOM. It is explicitly an educational experiment, not intended for production use.

## Use cases
- learn how virtual dom diffing works
- understand how react reconciles dom updates
- implement a minimal virtual dom from scratch
- teach dom diff and patch algorithms
- experiment with keyed list reordering
- study minimal frontend rendering internals

## When to choose
- you want a tiny readable codebase to study virtual dom internals
- you need a teaching or demo example of diff/patch algorithms
- you are building a toy framework for learning purposes

## When to avoid
- you are building a serious production application
- you need performance, security updates, or long-term maintenance
- you need a full-featured rendering solution like React or Vue

## Facets
- artifact type: library
- maturity: maintenance
- function: ui-components, frontend-framework
- domain: web-development, frontend, developer-tools, tutorials
- platform: browser
- tags: virtual-dom, diff-algorithm, educational, minimal, react-like, nodejs, javascript
