1
00:00:00,360 --> 00:00:07,230
Whoo hoo, we did it, we finished robo friends, we finished our wrap, now we can forget about it

2
00:00:07,230 --> 00:00:10,890
and it's going to live forever and ever on the Internet.

3
00:00:11,450 --> 00:00:11,880
Right.

4
00:00:12,600 --> 00:00:14,640
Well, maybe not.

5
00:00:15,570 --> 00:00:22,410
You see, part of using a library is something we've already talked about, a library or a framework

6
00:00:22,410 --> 00:00:25,560
is constantly evolving, constantly changing.

7
00:00:26,410 --> 00:00:32,380
And every time you use a tool, you usually want to stay up to date.

8
00:00:32,890 --> 00:00:38,230
This is one of the challenges with being a programmer that you always have to stay up to date.

9
00:00:38,500 --> 00:00:45,490
I mean, sure, your projects could live on on GitHub, but eventually they get stale.

10
00:00:46,030 --> 00:00:51,640
If they have a lot of dependencies or libraries that they depend on, then things might not work as

11
00:00:51,640 --> 00:00:52,270
intended.

12
00:00:52,840 --> 00:00:57,280
Now, this doesn't mean that you always have to jump on the latest and greatest.

13
00:00:57,400 --> 00:01:03,450
And as libraries come up with new features, you don't necessarily need to jump on them right away.

14
00:01:04,090 --> 00:01:12,100
But in these next couple of videos, I want to actually show you what my steps are and what most programming

15
00:01:12,110 --> 00:01:14,080
steps are when things change.

16
00:01:14,500 --> 00:01:20,770
Because if you have an application that is running, that has users, most of the time you want to keep

17
00:01:20,770 --> 00:01:21,540
things up to date.

18
00:01:22,150 --> 00:01:24,090
And this is something we've already talked about.

19
00:01:24,700 --> 00:01:31,420
But what about things like react we learned about react in this course and we're starting to get comfortable

20
00:01:31,420 --> 00:01:31,780
with it.

21
00:01:32,320 --> 00:01:39,340
But again, because it's a library, it gets updates because it's being used by companies like Facebook

22
00:01:39,520 --> 00:01:44,720
that has teams that constantly need new things, find challenges and want to improve it.

23
00:01:44,980 --> 00:01:47,340
Ideally, things are always improving.

24
00:01:48,160 --> 00:01:52,000
So React had a big update as a version sixteen point eight.

25
00:01:52,000 --> 00:01:53,760
It got something called hooks.

26
00:01:54,490 --> 00:02:01,150
Now, if you know anything about react, everybody is going a little crazy with hooks because there

27
00:02:01,150 --> 00:02:02,490
are quite a big shift.

28
00:02:02,530 --> 00:02:06,820
They are exciting, but can also be intimidating for a beginner.

29
00:02:07,600 --> 00:02:12,250
And you can see over here and there documentation that they have a new section on react hooks.

30
00:02:12,910 --> 00:02:17,950
Over the next couple of videos, we're going to be talking about react hooks, what they are, why they're

31
00:02:17,950 --> 00:02:18,490
useful.

32
00:02:19,000 --> 00:02:25,210
But instead of just showing you point by point, as it is in the documentation, how hooks work, because

33
00:02:25,420 --> 00:02:28,500
let's be honest, you're able to do that on your own.

34
00:02:28,960 --> 00:02:31,360
That's what these documentation's are for.

35
00:02:31,780 --> 00:02:38,410
I want to show you the process, how I would learn something new when a library changes, when a library

36
00:02:38,410 --> 00:02:39,340
has a new feature.

37
00:02:40,120 --> 00:02:47,170
Now, the reason I haven't talked about hooks up until now is that what even react documentation actually

38
00:02:47,170 --> 00:02:50,770
doesn't talk about hooks until way later in their guide.

39
00:02:51,220 --> 00:02:56,140
When you learn about react, their main concepts, some of the advanced guy, some API references,

40
00:02:56,350 --> 00:02:58,360
they don't mention hooks until the very end.

41
00:02:58,900 --> 00:03:04,930
So when you learn about react, it's good to put off hooks until you actually understand the concepts,

42
00:03:05,230 --> 00:03:07,440
which hopefully you do until now.

43
00:03:07,930 --> 00:03:10,530
So let's say Riak comes up with hooks.

44
00:03:10,540 --> 00:03:12,390
How would you go about learning it?

45
00:03:12,880 --> 00:03:19,360
Well, obviously you'd start off with the documentation and start going through it and actually understanding.

46
00:03:20,050 --> 00:03:23,620
Now, starting in the next video, we're going to learn about hooks, but I'm going to show you the

47
00:03:23,620 --> 00:03:32,680
process of how I would learn about hooks and then also convert our robo friends app from using the class

48
00:03:32,680 --> 00:03:38,950
stateful components to using react hooks so that you can compare them side by side and see what the

49
00:03:38,950 --> 00:03:39,640
differences are.

50
00:03:40,180 --> 00:03:41,670
I'll see in the next one by.
