00:00:02,344 --> 00:00:03,370
[Maximilian Schwarzm�ller] As you can probably
2
00:00:03,370 --> 00:00:08,270
tell by now we are diving deeper and deeper into React.
3
00:00:08,270 --> 00:00:10,860
And in this module, we're going to have a look
4
00:00:10,860 --> 00:00:14,170
at another core concept, which you will use
5
00:00:14,170 --> 00:00:16,820
in a lot of React apps you're going to build
6
00:00:16,820 --> 00:00:19,370
and that will be Custom Hooks
7
00:00:19,370 --> 00:00:23,350
and how you can build your own Custom Hooks.
8
00:00:23,350 --> 00:00:25,910
Now, up to this point in this course
9
00:00:25,910 --> 00:00:28,570
we already worked a lot with Hooks,
10
00:00:28,570 --> 00:00:31,770
with the built in React Hooks React offers
11
00:00:31,770 --> 00:00:36,019
to us like useState, UseReducer, UseEffect
12
00:00:36,019 --> 00:00:38,060
UseContext and so on.
13
00:00:38,060 --> 00:00:43,060
So all these special React functions that start with Use.
14
00:00:43,150 --> 00:00:45,880
You might remember that when I talked
15
00:00:45,880 --> 00:00:49,230
about the rules of Hooks, I mentioned that
16
00:00:49,230 --> 00:00:52,020
you can only use React Hooks
17
00:00:52,020 --> 00:00:56,770
in React Component Functions and in Custom Hooks.
18
00:00:56,770 --> 00:00:59,850
And I told you that those would be covered later.
19
00:00:59,850 --> 00:01:02,200
Well, now is later.
20
00:01:02,200 --> 00:01:05,519
Now we're going to explore how you can build your own Hooks,
21
00:01:05,519 --> 00:01:07,680
why you might want to do that,
22
00:01:07,680 --> 00:01:09,640
How exactly you do that, of course,
23
00:01:09,640 --> 00:01:11,518
And we're going to do that
24
00:01:11,518 --> 00:01:13,640
as a concrete example or multiple examples.
25
00:01:13,640 --> 00:01:17,350
And we're also going to learn about the rules
26
00:01:17,350 --> 00:01:20,880
and practices and best practices that apply when
27
00:01:20,880 --> 00:01:23,033
you build your own Custom Hooks.
