[Javascript] code deciphering help

[Rodney Myers]

This is the structure of the "inline conditional" :

                 variable = condition ? value_if_true : value_if_false

                 it is equivalent to :

                 if(condition)
                     {
                         variable = value_if_true;
                     }
                 else
                     {
                         variable = value_if_false;
                     }
