Need to take this basic code and create a quiz with the following requirements in Javascript:

- Click a start button

- timer starts

- presented with question

- once answered, another question is presented

- if answer is wrong, time is subtracted from timer

- when all questions are answered or time reaches 0, game is over

- able to enter my name and add to a list of high scores at the end of the game

var quizArray = [

{ q: "QUESTION 1", a: ["A","B","C","D"] },

{ q: "QUESTION 2", a: ["A","B","C","D"] },

{ q: "QUESTION 3", a: ["A","B","C","D"] },

{ q: "QUESTION 4", a: ["A","B","C","D"] },

{ q: "QUESTION 5", a: ["A","B","C","D"] }

];

var score = 0;

var turn = 0;

const startBtn = document.getElementById("startbtn");

const mainEl = document.getElementById("mainEl")

startBtn.addEventListener("click",startBtnClickHandler);

function startBtnClickHandler() {

startBtn.style.display = "none"

mainEl.appendChild(createQuestion(turn))

turn++

}

function createQuestion(index) {

const panel = document.createElement("div");

const question = document.createElement("h3")

const answers = document.createElement("ul")

question.innerText = quizArray[index].q

panel.appendChild(question)

for (var i = 0; i < 4; i++) {

const answer = document.createElement("li")

answer.innerText = quizArray[index].a[i]

answer.addEventListener("click", answerClickHandler)

answers.appendChild(answer)

}

panel.appendChild(answers)

return panel

}

function answerClickHandler() {

mainEl.removeChild(mainEl.lastChild)

mainEl.appendChild(createQuestion(turn))

turn++

}
