intermediate Published 20 Apr 2026
Action Steps
  1. Identify large lists in your React application that may be causing performance issues
  2. Use a virtualization library such as react-virtualized to only render visible items
  3. Configure the virtualization library to optimize rendering and scrolling performance
  4. Test and iterate on the virtualization configuration to achieve optimal performance
  5. Apply virtualization to other large lists in your application to improve overall performance
