Quick Note: Service Worker File

In the next video, we will start building our very first React Component. Hooray!

However, remember what I said in the previous videos when I introduced you to Create React App: CRA is constantly evolving... and the latest version of CRA includes extra files like the Web Vitals that we will ignore for now. One file you will see in the next video that no longer comes with the latest version of CRA is the 'registerServiceworker.js'. Therefore you can ignore the 'registerServiceworker()' in index.js that you will see in the next video since we will not be using it.
