## What it is
A TodoMVC reference implementation written in ~200 lines of modern (ES6+) vanilla JavaScript with no build tools, demonstrating that complex apps can be built without frameworks. It includes branches showing component architecture, performant DOM updates, lit-html integration, and TypeScript variants as a learning blueprint.

## Use cases
- learn how to build apps without a framework
- see a modern vanilla javascript todomvc example
- understand reactivity patterns with plain javascript
- compare vanilla js vs react for declarative UI
- find a minimal example of javascript modules with no build tools
- study component architecture in vanilla js
- learn efficient DOM rendering for lists

## When to choose
- learning modern vanilla JavaScript patterns without frameworks
- looking for a compact reference implementation of TodoMVC
- evaluating whether a framework is needed for a small app
- teaching or studying frontend architecture fundamentals

## When to avoid
- building a production application that needs a real framework ecosystem
- needing routing, state management libraries, or large-team tooling
- requiring a maintained, licensed dependency in a project

## Facets
- artifact type: learning-resource
- maturity: stable
- function: frontend-framework, ui-components, state-management, templating
- domain: web-development, frontend, education, tutorials
