const data = await apiRequest('/api/products');

// Show Notification
showToast('Product saved successfully!', 'success');

// Storage
storage.set('user', { name: 'John' });
const user = storage.get('user');

// Debounce Search
const searchDebounced = debounce(searchFunction, 500);
searchInput.addEventListener('input', searchDebounced);

// Format Currency
const price = formatCurrency(29.99); // "$29.99"
