‫Welcome to the race chapter.

2
00:00:01,980 --> 00:00:07,680
‫And this chapter you are going to see how race work, how lists work, how different types of a race

3
00:00:07,680 --> 00:00:13,290
‫work, and what different types of a race there are, what the use of a race is, and how we can iterate

4
00:00:13,290 --> 00:00:16,170
‫through a race and a bunch more.

5
00:00:16,740 --> 00:00:24,120
‫So this is a very important part of programming because very often you have a bigger set of data that

6
00:00:24,120 --> 00:00:28,080
‫you need to work through or that you want to use for a certain situation.

7
00:00:28,080 --> 00:00:34,560
‫So for example, let's say you have 100 users in your database and you want to change something for

8
00:00:34,560 --> 00:00:35,850
‫every single one of them.

9
00:00:35,850 --> 00:00:40,860
‫Well, that's where it would make sense to put them into an array or maybe in the list, depending on

10
00:00:40,860 --> 00:00:42,450
‫what you want to do with them.

11
00:00:42,810 --> 00:00:48,180
‫And you're going to see what the advantages of the two types are, so what the advantages of lists and

12
00:00:48,180 --> 00:00:50,430
‫arrays are and how to use them.

13
00:00:50,430 --> 00:00:53,850
‫And of course, there will be exercises as well and quizzes.

14
00:00:53,850 --> 00:00:54,210
‫All right.

15
00:00:54,210 --> 00:00:56,490
‫So let's dive right into this chapter.

16
00:00:56,490 --> 00:00:57,930
‫See you in the next video.
