React Lazy Loading is a powerful performance optimization technique that helps reduce the initial bundle size of your application by splitting code into smaller chunks and loading them on demand.
There are two main features provided by React for implementing lazy loading: React.lazy() and Suspense.
Lazy loading can be implemented in different scenarios such as simple component lazy loading, route-based lazy loading, and using advanced patterns like custom loading component, error boundary integration, and preloading components.
Some best practices for implementing lazy loading include choosing the right granularity, grouping related components, and handling loading states gracefully.
