At first glance I notice that the answer count is created as a string (let correctAnswer = "") and then later is concatenated with a digit (correctAnswer +=1) potentially several times. This is confusing as it appears as it is being incremented as a number.

It would be better to create it as a number to begin with (let correctAnswer = 0). Then later instead of checking the string length (if (+correctAnswer.length === 5)), the value could be checked directly (if (correctAnswer === 5)).

And for future questions, a better way to show your code is by making a snapshot of your workspace and posting just the link to it here.
