JavaScript Question

Question

Was playing the game and tried to test an answer so I can see what is happening, but I can’t get it to work:

Once working, I wanted to print every value I returns to see what’s happening.

What value is printed, which is apparently 6

Answer 1

correct js code:

var obj = {
arr: [1,2,3],
num:1
};

for (var i=0; i<obj.arr.length; i++) {
obj.num *= obj.arr[i];
}

document.write(obj.num);
