00:00:00,810 --> 00:00:05,470
I've updated the cheat sheet to retain the most important takeaways leading up to the function section.

2
00:00:06,030 --> 00:00:09,360
I added all of the function parts here we have the level of access.

3
00:00:09,760 --> 00:00:11,430
So far we've only used public.

4
00:00:11,430 --> 00:00:12,690
We still haven't used private.

5
00:00:12,690 --> 00:00:17,040
And that's only because it's only going to make sense once we cover object oriented programming.

6
00:00:18,230 --> 00:00:21,860
Right now in this module, we don't care too much about the level of access, so we're just going to

7
00:00:21,860 --> 00:00:22,970
keep everything public.

8
00:00:25,060 --> 00:00:30,040
And below are the remaining function parts, I also leave you with a rule of thumb that we talked about,

9
00:00:30,040 --> 00:00:34,210
which specifies that if our function calculates a value, it should return its.

10
00:00:39,400 --> 00:00:44,560
So if there's anything you need to revisit, whether it's this section or the one previous, all of

11
00:00:44,560 --> 00:00:48,700
the updated cheat sheets are unlearn the part and I'm going to see you in the big challenge.
