Question
What does this code print?
Code
function double(x) {
return x * 2;
}
console.log(double(7));
Hint
The function multiplies its input by 2.
Explanation
The function double takes a parameter x and returns x * 2. When called with double(7), x is 7, so the return value is 7 * 2 = 14. console.log prints that result: 14
