1
00:00:00,230 --> 00:00:02,030
We've covered a lot in this course.

2
00:00:02,030 --> 00:00:03,190
We've looked at packages,

3
00:00:03,190 --> 00:00:06,910
which let you break your program
into manageable components.

4
00:00:06,910 --> 00:00:10,270
Packages let you decide whether their
components should be exported for

5
00:00:10,270 --> 00:00:14,766
use by other packages or un-exported,
for use only internally.

6
00:00:14,766 --> 00:00:16,730
We learned about Go's static typing and

7
00:00:16,730 --> 00:00:20,610
how it can protect you from using
the wrong values in the wrong way.

8
00:00:20,610 --> 00:00:23,160
We learned about Go functions and
how Go's unique

9
00:00:23,160 --> 00:00:28,110
take on error handling helps ensure that
errors don't get away in your program.

10
00:00:28,110 --> 00:00:31,000
We learned how the Go format
tool can ensure you never have

11
00:00:31,000 --> 00:00:33,270
to look at another style guide.

12
00:00:33,270 --> 00:00:35,880
We learned about arrays,
slices and maps, and

13
00:00:35,880 --> 00:00:41,050
how to use the for range loop to easily
process all the values they contain.

14
00:00:41,050 --> 00:00:44,411
We learned to use structs to aggregate
fields of various types together.

15
00:00:44,411 --> 00:00:47,397
How to build custom types
on top of those structs.

16
00:00:47,397 --> 00:00:49,589
How to attach methods to those types and

17
00:00:49,589 --> 00:00:54,180
how to build interfaces that let you treat
multiple types as if they were the same.

18
00:00:55,450 --> 00:00:58,640
And we saw how to use Go routines and
channels to let your program

19
00:00:58,640 --> 00:01:03,970
carry out multiple tasks at the same time
and to communicate between those tasks.

20
00:01:03,970 --> 00:01:07,260
That's it for our lightning tour
of the Go Programming Language.

21
00:01:07,260 --> 00:01:11,600
It's a powerful tool for creating fast
programs that are easy to distribute and

22
00:01:11,600 --> 00:01:13,430
easy to maintain over time.

23
00:01:13,430 --> 00:01:17,330
See the teachers notes for some more
sources where you can learn more about Go.

24
00:01:17,330 --> 00:01:17,850
Happy coding
