• Moore Neighbourhood task errors


I would like to give some feedback about ...

Extra test 3/3 pass the error: TypeError: Cannot read property '3' of undefined, at ClientLoop.countNeighbours (evalmachine.:15:108), at ClientLoop.cover [as coverCode] (evalmachine.:4:17).

I don't know why the other tests have passed. The function template contains 3 parameters, the tests contain 1 array parameter.
