00:00:01,080 --> 00:00:02,490
‫Hey there.

2
00:00:02,490 --> 00:00:04,830
‫In this section, we're gonna go deep

3
00:00:04,830 --> 00:00:08,793
‫into some inner workings of React once again.

4
00:00:09,840 --> 00:00:13,530
‫So, we'll analyze renders in practical terms

5
00:00:13,530 --> 00:00:16,050
‫using this demo application

6
00:00:16,050 --> 00:00:20,310
‫and learn how to optimize wasted renders and performance

7
00:00:20,310 --> 00:00:25,080
‫in general using some more advanced React tools.

8
00:00:25,080 --> 00:00:27,810
‫This way, you'll be able to understand

9
00:00:27,810 --> 00:00:29,910
‫React apps even better

10
00:00:29,910 --> 00:00:34,500
‫and make them as fast and snappy as possible.

11
00:00:34,500 --> 00:00:38,490
‫We'll also go even deeper into the useEffect talk

12
00:00:38,490 --> 00:00:41,100
‫because there's still a few more things

13
00:00:41,100 --> 00:00:42,930
‫that we need to learn.

14
00:00:42,930 --> 00:00:46,980
‫So, this is another truly advanced section

15
00:00:46,980 --> 00:00:51,330
‫and one that I'm really excited to share with you.

16
00:00:51,330 --> 00:00:54,630
‫So, get ready to take a lot of notes

17
00:00:54,630 --> 00:00:58,020
‫and really take your React skills and understanding

18
00:00:58,020 --> 00:01:00,934
‫to the next level one more time.

19
00:01:00,934 --> 00:01:02,889
‫(upbeat music)
