weird browser reaction.

var dice = {
  sides: 6,
  roll: function () {
    var sides = 6;
    var randomNumber = Math.floor(Math.random() * dice.sides) + 1;
    console.log(randomNumber);
  }
}```

Hey Ivan,

You have to call the roll method... like this:

dice.roll();

does it suppose to give me an undefined line right after the random number?

Yup. It's because you didn't return anything from your function. Every function has a return method that's set to undefined by default. If you return the value of randomNumber, (as opposed to console.log(randomNumber)) the console will just show the random number.

Thanks Mikis, JavaScript is a little weirder for me, so I am having a little bit of "what a hell you doing" issues with the console :-)
