In this module, we converted our application to use functional components and React hooks only,
no more class-based components, no more lifecycle hooks, no more set state calls,
instead only functional components and hooks
and as you saw, we pretty much only used useState and useEffect.
Now the other hooks still have their purpose and definitely checkout the React hooks module in this
course to learn about them,
also of course checkout the official docs and simply play around with these hooks.
I hope that this module helped you see how you can convert an existing project and how you can think
about hooks and functional components.
Well and last but not least, we also created our own custom hook which hopefully also gave you an idea
of how you can outsource your own logic that even uses hooks as we do here with useState and useEffect
into your own custom hook that you could add into any functional component of your app.
