// 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
