## What it is
The canonical TodoMVC example application written in Elm, demonstrating the Elm Architecture with a single Main.elm file and localStorage persistence. It serves primarily as a beginner-friendly reference for learning Elm.

## Use cases
- learn elm from a small example
- see how the elm architecture works
- reference implementation of todomvc in elm
- starting point for a new elm app
- compare elm code with other todomvc implementations

## When to choose
- you are learning Elm and want a minimal, idiomatic example
- you want to see how Elm state updates and localStorage persistence work
- you need a small codebase to understand Elm before starting a project

## When to avoid
- you need a production-ready todo application with features beyond TodoMVC
- you are not using Elm and want a framework-agnostic example
- you need an actively developed app rather than a stable teaching example

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: frontend-framework, state-management, developer-tools
- domain: web-development, frontend, education, tutorials
- platform: browser, cross-platform
- tags: elm, todomvc, example-app, beginner-friendly, reference-implementation, web-server
