What is code splitting in React and how does it improve performance?

Code splitting allows you to divide your code into separate bundles, which can be loaded on demand. This enhances performance by:

• Reducing initial load time, as only the required code is fetched.
• Decreasing the size of JavaScript files sent to the browser.
• Enabling faster interactions by loading components only when needed (e.g., via React.lazy and React.Suspense). Consider trade-offs such as possible flickering as components load and managing user experience during load times.
