At the end, I even showed you how to describe the structure of complex types using the bracket syntax shown here. While this syntax is perfectly legal, and sometimes even useful, there is a better way to represent complex object structures like this, and that is with interfaces. To demonstrate, I'll convert this inline type into an interface. To create an interface, I'll simply use the keyword, interface, followed by the name of the interface that I'd like to create.
