## What it is
A minimal JavaScript framework implementing the Elm architecture: a single immutable state tree, pure update functions, actions, and a virtual DOM view layer built on Snabbdom. It doubles as documentation of the architecture, with examples ranging from counters to TodoMVC and FRP integration via Flyd.

## Use cases
- build a frontend app with the Elm architecture in JavaScript
- learn how unidirectional data flow frameworks work internally
- write frontend apps with pure functions and minimal mutation
- implement time-travel debugging and serializable state
- explore FRP-based state handling with Flyd
- study a minimal alternative to React/Redux

## When to choose
- you want a tiny, functional, Elm-style architecture without React
- you value testability through pure functions and inspectable state
- you're learning how virtual DOM and unidirectional architectures are implemented

## When to avoid
- you need a production framework with an active community and ecosystem
- you require TypeScript support or modern tooling out of the box
- the project has seen no releases since 2019 and is effectively dormant
