Why do we need React Developer Tools?
Since the chrome dev tools already shows the html markup rendered by React, what is the point of the React extension for a separate Dev tools?
In addition, React dev tools is not showing any information in the DOM tree except for the component names. It doesn't show classes or text inside of nodes.

the React dev tools show information specific to React components like state, props, source code and more additional profiling information. This can help debugging React applications a lot.
Also it seems the layout of the React dev tools extension changed a bit since the recording of the video. At least in the Chrome extension. But the principles are still the same for examining an application.
Hope this helps. Happy coding!
