How to call a function with a parameter in Javascript

Question

I am training in JavaScript on the TeamTreehouse website, I am stuck on a simple fill in the blank question.

function getRandom( upper ) {
 return Math.floor(Math.random() * upper) + 1;
}

The fill in part is

.............;

Answer 1

Here you go, its pretty simple:

getRandom(12);

Answer 2

getRandom(12)通常您会添加半冒号，但空白填充了该部分。
