‫Welcome to the race chapter.
‫And this chapter you are going to see how race work, how lists work, how different types of a race
‫work, and what different types of a race there are, what the use of a race is, and how we can iterate
‫through a race and a bunch more.
‫So this is a very important part of programming because very often you have a bigger set of data that
‫you need to work through or that you want to use for a certain situation.
‫So for example, let's say you have 100 users in your database and you want to change something for
‫every single one of them.
‫Well, that's where it would make sense to put them into an array or maybe in the list, depending on
‫what you want to do with them.
‫And you're going to see what the advantages of the two types are, so what the advantages of lists and
‫arrays are and how to use them.
‫And of course, there will be exercises as well and quizzes.
‫All right.
‫So let's dive right into this chapter.
‫See you in the next video.
