Functional solution

Hate to admit but OOP is not my strongest side, so for all of those who are in the same boat...

function Question(text, choices, answer) {
    this.text = text;
    this.choices = choices;
    this.answer = answer;
}
let j = 0;
let score = 0;
function createQuestion () {
  if (j === questions.length) {
    document.querySelector('#quiz').innerHTML = `You answered ${score} questions correctly out of ${questions.length}`;
  } else {
    document.querySelector('#progress').innerHTML = `Question ${j+1} out of ${questions.length}`;
    document.querySelector('#question').innerHTML = questions[j].text;
    document.querySelector('#choice0').innerHTML = questions[j].choices[0];
    document.querySelector('#choice1').innerHTML = questions[j].choices[1];
  }
}
document.addEventListener('click', e => {
  if (e.target.tagName !== 'BUTTON') { return; }
  if (e.target.tagName === 'BUTTON' && e.target.previousElementSibling.textContent === questions[j].answer) { score++; }
  j++;
  createQuestion(questions);
});
createQuestion(questions);
