In this example, starting in my main.go file in the practice directory in this branch, I have my variable called colors. And I'm explicitly declaring it as a variable with three items. And when I run the code, I get the expected output of red, green, blue. Now, this is an array, not a slice. And the reason is because I set an explicit number of items. I set the length. If I remove that number, now it's a slice and you can add and remove items, sort it, and so on. If I run this code, it looks exactly the same but now I'll add an item.
