## What it is
An educational project that dissects Vue's two-way data binding (MVVM) implementation and provides a simplified hand-written MVVM library built with Object.defineProperty. It includes a companion article explaining the Observer, Compile, and Watcher modules, plus a Vue 3 reactivity demo.

## Use cases
- understand how vue implements two-way data binding
- learn how to build a simple mvvm framework from scratch
- study Object.defineProperty getter/setter data hijacking
- read a simplified version of vue source code before diving into the real codebase
- see how observer, compiler, and watcher fit together in reactivity
- learn the vue3 proxy-based reactivity principle

## When to choose
- you want to deeply understand vue's reactivity internals
- you are learning frontend framework design patterns
- you need a minimal teaching implementation of mvvm data binding

## When to avoid
- you need a production-ready frontend framework
- you need array mutation handling, circular dependency support, or full vue features
- you want an actively maintained library with a license and community support

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: state-management, frontend-framework, developer-tools
- domain: web-development, frontend, tutorials, programming-languages
- platform: browser, cross-platform
- tags: mvvm, vue, data-binding, reactivity, educational, defineproperty, observer-pattern, nodejs
