How data flows in Redux apps

• User does something in the UI (e.g., clicks, submits form, toggles checkbox).
• Action is dispatched, perhaps with some payload (e.g., new input box value). You’ll have to configure what actions are dispatched for what events.
• Dispatched actions are sent to the Store. Store runs the action through its reducers – functions that take a state and action, and compute a new state.
• State is updated.
• UI is re-rendered based on the new state.
