Where does "greeting" come from?

Also, why is that is written like: greeting => console.log()

and not
var greeting = () => console.log()

Not sure what you're meaning exactly. Is this a question from a course or challenge or something? The Arrow Function shorthand syntax:

greeting => console.log();

...allows you to declare a function that takes a single parameter (greeting) and returns a single expression (console.log()). I'm not really sure what use there is, since you're not logging anything to the console. I could see this as being more useful:

var saySomething = greeting => console.log(greeting);
saySomething('hello');
// logs 'hello' to console
