In this session, you will learn how to implement code splitting and lazy loading for routes in a React application using React Router. This technique optimizes performance by loading only the necessary code for a route when it's accessed, improving initial load time and overall user experience. Let's start where we left off in the previous session. Ok, now we are beginning to optimize our routes. I am importing Suspense and Lazy from React. Suspense will allow us to display a fallback component while the LazyLoaded component is being fetched. The Lazy function enables us to dynamically import components when they're needed. Let's add a comment to clearly mark the section where we'll place our lazy-loaded components. This helps with code organization and readability, especially as the application grows. These are the components designated for lazy-loading. To prepare for lazy-loading, let's rearrange the imports. We'll keep the components that will remain statically imported at the…
