Minimize layout thrashing and reflows by using CSS techniques like flexbox and grid layout.
Reduce unnecessary repaints by using CSS transitions and animations sparingly.
Use hardware-accelerated CSS properties like transform and opacity for animations.
Lazy load images and other assets to prevent blocking the main thread.
Code Splitting:
Implement code splitting to load only the necessary JavaScript and assets for the current view. This improves initial load times and reduces the amount of JavaScript executed.
State Management:
Choose an efficient state management solution like Redux to ensure that UI updates are minimal and localized.
Caching and Compression:
Implement browser caching for static assets and enable GZIP/BR compression on your server to reduce transfer times.
Cross-Browser Testing:
Test your UI in various browsers and devices to ensure consistent performance across different environments.
Content Delivery Networks (CDNs):
Utilize CDNs for delivering assets to users from locations closer to them, reducing latency.
