In React, lazy loading is often achieved using the built-in React.lazy() function and the <Suspense> component:
-  React.lazy():-  A function that allows you to dynamically import a component.
-  It returns a component that React can render as usual.
 
-  
-  <Suspense>:-  A component that wraps the lazy-loaded components.
-  It displays a fallback (e.g., a spinner or a message) while the lazy-loaded component is being fetched and rendered.
