Practical optimizations you can apply today
Wrap CPU-heavy calculations in useMemo to avoid recalculating on every render cycle.
Render only visible rows with a virtualizer instead of mounting thousands of DOM nodes at once.
Use dynamic imports to load page-specific bundles on demand and shrink initial JavaScript payload.
Delay state updates from search fields and sliders to prevent excessive re-renders during typing.
Keep state as close to where it is used as possible so parent components skip unnecessary re-renders.
