00:00:05,660 --> 00:00:11,150
In this section, we are going to talk about the three different types of strokes with the main one

2
00:00:11,150 --> 00:00:12,860
being a named field stroke.

3
00:00:12,890 --> 00:00:19,100
Strokes or strokes are important because it will help us group together similar values into a one value

4
00:00:19,100 --> 00:00:20,360
like variable.

5
00:00:20,480 --> 00:00:26,210
We are also going to go over lifetimes and what they are and why they exist, as well as the history

6
00:00:26,210 --> 00:00:28,610
behind them and how they continue to evolve.

7
00:00:29,090 --> 00:00:35,780
The concepts that we learn in this section will be continued to get used throughout the lifetime of

8
00:00:35,780 --> 00:00:36,320
this course.

9
00:00:36,320 --> 00:00:42,170
So it is important to make sure we understand how strokes are used, as we will use them very extensively

10
00:00:42,170 --> 00:00:50,420
as we continue our journey as well as lifetimes, because lifetimes are going to influence how we organize

11
00:00:50,900 --> 00:00:51,710
our code.
