CodeAcademy DetectGoodInput Lesson
In the lesson for Basic Functions: Javascript Quick Start: Start Guide, part 4, Return Values:
The presented problem:
// If value is falsy…
The instructions give a hint on what to add, or rather what NOT to add:
You do not need to have Return ‘undefined’; as part of the IF statement.
so,
if (is falsy and not a string){} // put NOTHING in the {}
else
return ‘good input!’;
