What’s the best way to reduce performance in react?
If your application renders long lists of data (hundreds or thousands of rows), we recommend using a technique known as “windowing”. This technique only renders a small subset of your rows at any given time, and can dramatically reduce the time it takes to re-render the components as well as the number of DOM nodes created.
