Do you remember what the original code looked like? Was it using console.log or doing something else?
//
// This is only a SKELETON file for the 'Hello World' exercise. It's been provided as a
// convenience to get you started writing code faster.
//
export function hello() {
return 'Goodbye, Mars!';
}
This is what that looked like as delivered (in content, not necessarily style).
Instead of using console.log() which is focused on output to your display device, this is testing functionality, not display. In other words we are looking for a return from a function named hello() and not just output to the screen or log.
