What strategy we have implemented to optimize our React application for performance? And can you give specific examples? Yeah. We've used memoization with the `useMemo` hook. We've also optimized unnecessary expensive calculations based on their dependencies. You can call the `useMemo` function to memorize a function and redefine its dependency by passing the view reference to the function. And we've split our React components into lazy-loaded ones using `React.lazy` and `Suspense`.

You react to having experienced performance issues with profiling, so you wanted to render and state updates. How you identify and alleviate this problem? In the React application experience, the performance is due to successful rendering and frequent state updates. So, you can use the developer tools to profile in the Chrome application. You'll have to use another profile tab and have to remove unnecessary re-rendering and reduce render times and highlight the objects.

Describe a scenario where is server side rendering drastically improved variant apps performance? What was the impact on SEO and overall user experience? Server side rendering, I imagine the ecommerce platform when the users now the thousands of products. So application users are rendering the product and leasing the piece file, the data of client side. And the user experience, I like to experience the delay before the piece fully loaded and because the initial HTML pass only the root deep, so can product data as well as the render after the JavaScript has executed.
