As we saw in the previous lecture, a variable block is perfectly valid even if it has no arguments defined inside. In this case, since we have not specified a default value, we would have to pass in the values during the Terraform execution using one of the several methods that we saw earlier. A default value may be added for any variable using the default argument. We can also optionally add a description. It's a good practice to make use of this argument to specify what this variable is used for. Then we have the type argument, which as the name suggests, defines the type of data that the variable accepts. Another optional argument is sensitive.
