 Learning how to use `this` in JavaScript is something of a rite of passage.
 Since TypeScript is a superset of JavaScript, TypeScript developers also need to learn how to use `this` and how to spot when it's not being used correctly.
 Fortunately, TypeScript lets you catch incorrect uses of `this` with a couple of techniques.
