Here is my solution

// 1. Create a multidimensional array to hold quiz questions and answers
const quiz = [
  ['What is Mooning?', 'Bitcoin'],
  ['Why is mooning?', 'Tis Best Coin'],
  ['Do you have enough?', 'No']
];

// 2. Store the number of questions answered correctly
let correct = 0;
let incorrect = 0;

/* 
  3. Use a loop to cycle through each question
      - Present each question to the user
      - Compare the user's response to answer in the array
      - If the response matches the answer, the number of correctly
        answered questions increments by 1
*/

const correctAnswers = [];
const incorrectAnswers = [];


for (i = 0; i < quiz.length; i++) {
  let response = prompt(quiz[i][0]);
    if ( response === quiz[i][1] ) {
      correct++
      correctAnswers.push(quiz[i][0]);
    }
    else {
      incorrect++
      incorrectAnswers.push(quiz[i][0])
    }
};

function createListItems(arr) {
  let items = '';
  for (let i=0; i < arr.length; i++) {
    items += `<li>${arr[i]}</li>`;
  }
    return items;
}

// 4. Display the number of correct answers to the user

document.querySelector('main').innerHTML = `
  <h1>You got ${correct} answsers correct!</h1>
  <h2>You got these questions correct:</h2>
  <ol>${ createListItems(correctAnswers) }</ol>

  <h2>You got these answers incorrect!</h2>
  <ol>${createListItems(incorrectAnswers)}</ol> `
