Flux Architecture คืออะไร?

  Action  →  Dispatcher  →  Store  →  View

         (user interaction creates a new Action)

1. Action     — a plain object describing WHAT happened ({ type: 'ADD_TODO', text })
2. Dispatcher — a central hub that sends every action to the stores
3. Store      — holds state + logic; updates itself in response to actions
4. View       — renders from the store; user interactions dispatch new actions
