Something wrong with the code on the video..

Is he forgot to declare var html? because at the end of the code it was "html = "You got " + correctAnswers + " question(s) right."".

It would be "best practice" to declare the variable, but unless the script is running in "strict" mode, implicit globals are allowed and will not cause an error.

I expect this was done unintentionally, and is not an example of recommended practice.
