Hi, @adrianhajdin , First of all I want to thank you for your amazing work and opportunities you give us. I decided to learn Next.js and I think your course will be one of the best resource. But now, I want to ask your advice related to optimization for react applications(without Next.js). I noticed that you dedicated your time to increase the performance of your application up to 90 and more. If you have an opportunity to help me I'd be very thankful. I checked the page speed and it recommends to reduce unused Javascript. Here are the files. Especially I do not understand how to reduce unused code related to react-dom(I underlined it). This project was bootstraped with create-react-app and I did not add any configurations to webpack image

Hi @Lenur29, maybe you could read following articles to understand what is a minified file.
