 -----------------------------------
 
 When a page loads, all components are rendered immediately. If a component is
-heavy to render, you can defer its rendering after the page has loaded.

-Moreover, some components are not needed until the user scrolls to them (like
-components at the bottom of a long page like comments, related products, etc.).
-In this case, you can load them "lazily" when they are in the viewport.

-By loading a component asynchronously, the page will load faster and the user
-will be able to interact with it sooner, improving both the user experience
-and the overall performance of your application.
