JavaScript JavaScript Loops, Arrays and Objects Tracking Multiple Items with Arrays Build a Quiz Challenge, Part 1

Working code vs what I tried to do...

I tried two different approaches with the 'for loop' in this challenge.


The first 'for loop' works, which was a few more steps as I had to set up two different variables for the question and answer and then compare them. I also had to use parseInt to ensure the input from the prompt was converted to an integer.

The second for loop does not work and only returns 0. Am I trying to squeeze in too much functionality into the following line? I'm guessing it has to do with parseInt.

if (parseInt(prompt(quizArr[i][0]) === quizArr[i][1])) {

You just need to relocate a parenthesis so parseInt only applies to the prompted question:

if (parseInt(prompt(quizArr[i][0])) === quizArr[i][1])
