/* For portion of the assignment your job is to write functions

* so that each function invocation below works. You're working backwards.

*

* There are no tests for this file.

*

* Example:

*

* greeting('Hey guys', (message) => {

* console.log(message);

* });

*

* You would then define the greeting function to make the invocation work.

*

*

* const greeting = (str, cb) => {

* cb(str);

* };
