Please describe how to reproduce this issue, and include links to screenshots if possible.

Someone came into the help room on gitter asking why he didn't pass the challenge with functionWithArgs(); (which is correct), but did pass with functionWithArgs( ); (note the extra space). I tested it and the second indeed passes all tests. Seems necessary to test for passing proper arguments.
