I've updated the cheat sheet to retain the most important takeaways leading up to the function section.
I added all of the function parts here we have the level of access.
So far we've only used public.
We still haven't used private.
And that's only because it's only going to make sense once we cover object oriented programming.
Right now in this module, we don't care too much about the level of access, so we're just going to
keep everything public.
And below are the remaining function parts, I also leave you with a rule of thumb that we talked about,
which specifies that if our function calculates a value, it should return its.
So if there's anything you need to revisit, whether it's this section or the one previous, all of
the updated cheat sheets are unlearn the part and I'm going to see you in the big challenge.
