DRY & KISS Principles

What aspect of state management in this React component violates the KISS principle?

function UserDashboard() {
  const [isLoading, setIsLoading] = useState(false);
  const [error, setError] = useState(null);
  const [data, setData] = useState(null);
  const [activeTab, setActiveTab] = useState('profile');
  const [isEditing, setIsEditing] = useState(false);
  const [editData, setEditData] = useState(null);
  const [validationErrors, setValidationErrors] = useState({});
  const [isSaving, setIsSaving] = useState(false);
  const [showConfirmDialog, setShowConfirmDialog] = useState(false);

  // Multiple useEffect hooks and handlers managing these states
}

The state variables should be renamed
The component lacks proper types
The state management is overly complex
This code violates the KISS principle by implementing overly complex state management with too many independent state variables. A better approach would be to use a reducer or combine related states: function UserDashboard() { const [state, setState] = useState({ status: 'idle', // idle, loading, saving, error data: null, activeTab: 'profile', edit: { isEditing: false, data: null, validationErrors: {} }, showConfirmDialog: false }); const updateState = (updates) => { setState(prev => ({ ...prev, ...updates })); }; // Simplified state updates } This approach: 1. Reduces the number of state variables 2. Groups related state together 3. Makes state updates more predictable 4. Simplifies component logic
The useState hooks should be combined
