## What it is
Stimulus is a modest JavaScript framework that augments server-rendered HTML with interactive behavior using data-controller, data-target, and data-action attributes. It pairs with Turbo as part of the Hotwire stack, managing controller lifecycles as the DOM changes without taking over rendering.

## Use cases
- add interactivity to server-rendered HTML without a SPA framework
- build a Hotwire app with Rails and Turbo
- sprinkle JavaScript behavior onto existing HTML pages
- wire up DOM controllers with data attributes
- avoid heavy client-side rendering in a web app
- handle Ajax-updated DOM elements with automatic lifecycle management

## When to choose
- you have server-rendered HTML and want lightweight interactivity
- you use Rails or another backend with Turbo
- you want to avoid a full SPA framework like React
- you prefer progressive enhancement over client-side rendering

## When to avoid
- you need a full client-side SPA with complex state management
- you want a framework that renders HTML from components
- you're building a highly interactive canvas or real-time graphics app
