// increase score by 1
score++;
} else {
alert("Wrong!");
}
}
An
if ... else
block is then used, depending on whether the answer is right or wrong.
If it is right, then an alert dialog is shown saying that it is correct and the score is incremen-
ted by 1, using
score++
. Otherwise, if the answer is wrong, an alert dialog informs the
player.
When the loop has finished iterating through each question in the
questions
array, we
finish by using another alert dialog to inform the player that the game is over and tell them
how many questions they answered correctly:

(excerpt)
alert("Game Over, you scored " + score + " points");
