Can someone explain?

In the second output, we’ve initialized “O” using a simple variable instead of a short declaration operator whose value does not retain when we come out of its scope. So the output of the first quiz is GOG. But on re-calling the n function in the second quiz, we get GOO because we’ve not used the short declaration operator here.
