Spartacus

I like the TV series Spartacus so much, that I have written the following code to get the name of the different seasons but something goes wrong...

var season = 'first';

var result = ('Spartacus: ' + season === 'first' ? 'Blood and Sand' : 'Gods of the Arena');

I expected to get Spartacus: Blood and Sand but I got Gods of the Arena, could you help me?

Fix the code to get 'Spartacus: Blood and Sand':

var season = 'first';
var result = ('Spartacus: ' + season === 'first' ? 'Blood and Sand' : 'Gods of the Arena');

var season = 'first';
var result = 'Spartacus: ' + (season === 'first' ? 'Blood and Sand' : 'Gods of the Arena');

assert(result === 'Spartacus: Blood and Sand');
