## What it is
A JavaScript library that implements React's mixin strategy for ES6-style classes, allowing mixins to be applied to class prototypes or classes directly, including via decorators. It is explicitly positioned as a migration path for legacy code, since React mixins are deprecated in favor of higher-order components.

## Use cases
- add mixins to React ES6 class components
- migrate legacy createClass mixins to ES6 classes
- use PureRenderMixin or react-router Lifecycle mixin with classes
- apply mixins via ES7 decorators
- convert old mixins to UNSAFE_ lifecycle format for React 16.3+

## When to choose
- maintaining a legacy React codebase that still relies on mixins
- temporarily bridging createClass-era mixins into ES6 class components
- you specifically need a mixin like PureRenderMixin with class syntax

## When to avoid
- starting a new React project - use higher-order components or hooks instead
- using modern React versions where mixins are fully unsupported
- you want long-term maintained tooling - the project itself calls mixins 'basically dead'
