JavaScript Quiz, next question issue.

Hello,

I am trying to create a quiz to improve my JavaScript skills but I have got stuck on a certain part. On line 122 of my programme, I want the programme to clear the current question and answers then run the function again to create a new one when the next button is pressed.

Just implementing the steps you described (plus clearing the contents of the elements that will be re-used):

    } else if (buttonPress.className === "nextButton") {
      body.removeChild(questionDiv);                             // remove the old question
      questionDiv.innerHTML = "";                                // clear the contents
      ul.innerHTML = "";                                         // also clear the answer list
      createQuiz(Math.floor(Math.random() * questions.length));  // run the function again
    } else {  //...

You might want to select questions sequentially instead of randomly, as it's possible right now to get the same question twice in a row.

Hi, thank you very much for your help. Didn't realize it'd be as simple as that.

I am aware of the duplicate questions issue and was implementing a way to prevent getting the same questions but wanted to fix the button first.
