How can I optimize the performance of my React app?

There are several strategies you can use to optimize your React app's performance, such as code splitting, lazy loading, and memoization. Would you like to dive deeper into any of these?

Yes, can you explain code splitting?

Code splitting allows you to split your code into smaller chunks, which can be loaded on demand. This reduces the initial load time of your app. You can implement it using dynamic imports with React.lazy.

What about lazy loading images?

Lazy loading images means loading images only when they are about to enter the viewport. This can significantly improve your app's performance, especially if it has many images. You can use the loading='lazy' attribute in your image tags.

Are there any tools to help with performance monitoring?

Yes, tools like Lighthouse, React Profiler, and WebPageTest can help you monitor and analyze your app's performance.
