Clean architecture: * Model-View-Controller (https://en.wikipedia.org/wiki/Model%E2%80%93view%E2%80%93controller) * User triggers actions by using view or controller * Actions are part of model and they manipulate state that is stored * Actions can use services to interact with external (backend) systems * State changes trigger view updates * Selectors select and calculate a transformed version of state that causes view updates * Views contain NO business logic * There can be multiple interchangable views that use same part of model * A new view can be created to represent model differently without any changes to model * View technology can be changed without changes to the model
