Embrace the State Machine Paradigm

A state machine consists of defined states, actions that propose changes to these states, and a function that processes these actions alongside current states to produce new states. This structured approach enhances program reliability by allowing for precise management of events, such as debouncing multiple rapid user inputs into a single coherent action. Instead of directly mutating state, representing changes as transitions driven by actions and events simplifies the handling of user interactions and minimizes unintended consequences. Additionally, this paradigm includes three fundamental components: the model, which reflects the application's state; the view, which represents information to users; and the action, which delineates methods for altering the model. This framework facilitates a clearer understanding of state transitions and their effects on application behavior.
