-In this example, we're expecting `10 - 0` but have accidentally thrown in a new line during a copy + paste session (this always happens to me) that changed the type from a number to a string. As a result of this errant line, instead of `newNumber` being a number, it's now `NaN`.

 While TypeScript does not restrict the ability to have `NaN`s and errant copy-pastes (oh how I wish it did), it can make it more obvious that mistakes like this have been made by marking `numberHere` as a number type explicitly.

 When working on projects with objects that contain many properties that are used variously across files and functions, it can be difficult to track down what properties and methods are available to you without having to refer to the documentation of that scope in your application. With types present in your code, you're often able to reference that type (_often with a "jump to declaration" shortcut feature that is present in many IDEs_) to quickly refer to the properties and methods present on a given value or class.
