I am getting this error from this line of code : let question = questions[i][0];
I am not sure what I am doing wrong. Any help would really be appreciated.

To share the entire project, make a snapshot of your workspace and post the link to it here.

231,172 PointsNow that I've seen the snapshot, it was my first guess. On line 4 of quiz.js, there should be a comma at the end of the line to separate the second question from the third. Without it, the contents of the array's second element are undefined.
