Show Suggested Answer

Suggested Answer: C

objA is { value: 10 }.

objB = objA; both variables reference the same object.

changeValue(objB);:

obj.value = obj.value / 2; // modifies the shared object

So:

objA.value becomes 10 / 2 = 5.

Thus result is 5.

I'm not entirely sure, but since objB is a reference to objA, I guess the value would be 5 after the function runs.

I think the function changes the value of the object directly, so objA should also be affected.
