npm i
npm run dev
May need to cancel and run dev again.
Navigate to localhost:3000
See that hydrate does not log anything.
Click the "Click" button, it should log something.
Change the following line in `./src/containers/Inner.jsx' from
ReactDOM.hydrate(<Inner />, document.getElementById('app'));
to
ReactDOM.render(<Inner />, document.getElementById('app'));
The console log should now show for both the image loading and click.
