Which browser and which version you are using???

It seems a browser behavior error which return undefined instead of null when the searched storage item does not exist yet

Try to change this line : let scores = JSON.parse(localStorage.getItem('scores')) || { wins: 0, losses: 0 };

into

let scores = JSON.parse(localStorage.getItem('scores')||null) || { wins: 0, losses: 0 };
