No, I don't think that's appropriate, because it will pick 10 individual 
characters from a, b, c, ... , z (i.e. no character will appear more than once), 
and the characters picked will appear in alphabetical order.

Incidentally, if lowercase has the .length property, there's no need to pass the 
length separately to randomSample.  Just passing lowercase itself and the number 
of sample points desired is sufficient.
