Takes No Arguments But Has A Return Value

In addition to receiving data, functions can also return values back to the code that called them. Difining those functions is done by adding -> along what will be send back behindg the parenthesis after the name. For example

widget() -> String

The parts of the function look like this:

1. The fn keyword
2. A name
3. An empty set of () parenthesis.
4. The -> symbol followed by what type of data will be returned
5. A set of {} curly brackets surrounding the function's code block
