The answer
Add an input listener. Filter items by name (case-insensitive): item.name.toLowerCase().includes(query.toLowerCase()). Re-render the menu on every input. Debounce the search (300ms) to avoid excessive re-renders.

Store filter state (veg: true/false/null, category: string, maxPrice: number). In the filter function, check each condition. Re-render on every filter change. Combine search and filters in one getFilteredItems function.
Yes. Debounce the search input (300ms) to avoid re-rendering the menu on every keystroke. This improves performance, especially with large menus or when the search triggers an API call.
Check if the filtered items array is empty. If so, show a message like 'No items found' or 'No items match your filters' instead of the item list. This is better than showing a blank screen.
