-// From the serde_json docs:
-//
-// > There are three common ways that you might find yourself needing to work
-// > with JSON data in Rust.
-// >
-// > 1. As text data. An unprocessed string of JSON data that you receive on an
-// >    HTTP endpoint, read from a file, or prepare to send to a remote server.
-// > 2. As an untyped or loosely typed representation. Maybe you want to check
-// >    that some JSON data is valid before passing it on, but without knowing
-// >    the structure of what it contains. Or you want to do very basic
-// >    manipulations like insert a key in a particular spot.
-// > 3. As a strongly typed Rust data structure. When you expect all or most of
-// >    your data to conform to a particular structure and want to get real work
-// >    done without JSON’s loosey-goosey nature tripping you up.
-//
-// So let's take a look at all three...
