So the first one I want to point out is something called a local. And the name local is a little bit confusing. This is what you might think of in another programming language as a variable. Variable has another meaning in Terraform, and we're going to go over that in another section. But it's just a way of storing a value that you can refer to later. So in this first example, we're just storing a simple string. But we can do other things. We can store the result of an expression in a local.
