00:00:01,230 --> 00:00:05,940
‫Probably 95% of all React apps out there

2
00:00:05,940 --> 00:00:09,930
‫fetch some kind of data from some API,

3
00:00:09,930 --> 00:00:13,140
‫making data fetching an essential skill

4
00:00:13,140 --> 00:00:16,230
‫when building web applications.

5
00:00:16,230 --> 00:00:20,100
‫Now, one way of fetching data in a React app

6
00:00:20,100 --> 00:00:22,230
‫is inside an effect

7
00:00:22,230 --> 00:00:26,310
‫and so that's what this section is all about.

8
00:00:26,310 --> 00:00:29,460
‫So in this section, we'll continue working

9
00:00:29,460 --> 00:00:31,590
‫on the usePopcorn project

10
00:00:31,590 --> 00:00:35,130
‫as we learn all about side effects.

11
00:00:35,130 --> 00:00:38,280
‫So we're gonna focus on the useEffect Hook,

12
00:00:38,280 --> 00:00:41,520
‫how and when effects are executed,

13
00:00:41,520 --> 00:00:44,820
‫and how we can clean effects up.

14
00:00:44,820 --> 00:00:48,600
‫And loading external data into our applications

15
00:00:48,600 --> 00:00:53,600
‫finally makes them feel a lot more real-world and alive,

16
00:00:53,910 --> 00:00:56,523
‫and so let's quickly get started.
