00:00:02,230 --> 00:00:09,520
In this module, we converted our application to use functional components and React hooks only,

2
00:00:09,610 --> 00:00:14,920
no more class-based components, no more lifecycle hooks, no more set state calls,

3
00:00:14,950 --> 00:00:17,530
instead only functional components and hooks

4
00:00:17,530 --> 00:00:22,450
and as you saw, we pretty much only used useState and useEffect.

5
00:00:22,480 --> 00:00:28,030
Now the other hooks still have their purpose and definitely checkout the React hooks module in this

6
00:00:28,030 --> 00:00:29,760
course to learn about them,

7
00:00:29,830 --> 00:00:34,050
also of course checkout the official docs and simply play around with these hooks.

8
00:00:34,060 --> 00:00:39,730
I hope that this module helped you see how you can convert an existing project and how you can think

9
00:00:39,730 --> 00:00:42,340
about hooks and functional components.

10
00:00:42,370 --> 00:00:48,670
Well and last but not least, we also created our own custom hook which hopefully also gave you an idea

11
00:00:48,910 --> 00:00:55,540
of how you can outsource your own logic that even uses hooks as we do here with useState and useEffect

12
00:00:55,930 --> 00:01:00,970
into your own custom hook that you could add into any functional component of your app.
