JavaScript JavaScript Arrays Multidimensional Arrays Improve the Quiz – One Solution

My Solution

 // 1. Create a multidimensional array to hold quiz questions and answers

const quiz = [
       ['What is 2 + 2', '4'], 
       ['What animal has a very long neck', 'giraffe'], 
       ['What is the capital of Canada', 'ottawa']

// 2. Store the number of questions answered correctly and incorrectly
let correctAnswers = 0;
const correctQuestions = [];
const incorrectQuestions = [];

  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

for (let i = 0; i < quiz.length; i++) {
  let answer = prompt(`${ quiz[i][0] }`);

  if (answer.toLowerCase() === quiz[i][1] ) {
    correctAnswers += 1;
    correctQuestions.push('<li>' + quiz[i][0] + '</li>');
  } else {
    incorrectQuestions.push('<li>' + quiz[i][0] + '</li>');


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

document.querySelector('main').innerHTML = `
<h1>Your Score is ${correctAnswers} out of ${quiz.length}</h1>
<h2>You got these questions correct:</h2>
<h2>You got these questions incorrect:</h2><ol>${incorrectQuestions.join('')}</ol>`;
