Memoization in React prevents unnecessary re-renders by using React.memo, useMemo, and useCallback to cache components, values, and functions. This optimization technique ensures components only update when their dependencies change.

Code splitting reduces React bundle size by dynamically importing components with React.lazy. This optimization technique splits your application into smaller chunks, loading components on demand to improve initial load times.

Virtualization renders long lists efficiently in React by only displaying visible items on the screen. This technique prevents slow rendering and ensures a responsive UI when handling large data tables.

Use useMemo and useCallback to optimize React app performance when dealing with expensive calculations or passing callbacks to memoized child components. These hooks prevent unnecessary re-renders by caching values and functions.

React.lazy works with components to fix slow rendering by enabling code splitting for dynamic imports. It is most effective for optimizing complex dashboards and routes where components can be loaded on demand.

Frequent updates in React dashboards cause stuttering due to inefficient handling of long lists and excessive re-renders. Applying memoization and virtualization techniques optimizes the complex components for a smooth interface.
