The code below outputs the following using console.log:

1
2
3
3

• The first console.log(a.foo) outputs 1, which is the initial value of val in class A.
• The second console.log(b.foo) outputs 2, which is the initial value of val in class B.
• The third console.log(b.val) outputs 3, which is the value of val after setting it to 3 in b.foo = 3.
• The fourth console.log(b.foo) also outputs 3, since b.foo is a getter method that returns the value of val.
