prompt(question)

for ( var i = 0; i < questionAnswer.length; i++){ question = questionAnswer[i][0]; answer = questionAnswer[i][1]; respond = parseInt(prompt(question)); }

i know that in a loop if u use i++, it adds one to the loop, but prompt(question) = [i][0]. doesn't "prompt(question)" just ask [i][0] again?

Since the value of i increases with each pass through the loop, the question at [i][0] will be different each time (it will go from [1][0] to [2][0] to [3][0] to [4][0] to [5][0]).
