Chore Door!

gameOver('win') 

const gameOver = (status) => {

    if (status === 'win' ){

        startButton.inner = 'Good luck!' ;

    }

}

以上無法 hoisting，跑不出結果。

但是  gameOver('win') 是包覆在其他 "函數體內"是OKay的。

const numClosedDoors = 3;    <------改成 let numClosedDoors = 3;

const playDoor = ( ) => {

    numClosedDoors --;    <--------------- const numClosedDoors 常數無法 --

    if (numClosedDoors === 0) {

        gameOver('win')

    }

}
