Im building a checkbox quiz in JavaScript, Ive been trying my methods to get scores, but I could not.

how to do checkbox quiz questions and get scores if the answers are correct?

I have no code on HTML, only a form tag with id=form

Script var quiz = document.getElementById("form"); var question; var answer; var all; var choices; var questions = ! I{ t: "11", ac: ["a", "b", "c"], a: ("a") [{t: "21", ac: ["a", "b", "c"], a: ["a", I{ t: "31", ac: ["a", "b", "c"), a: ["b", "c"]}], function quizQ() { 11 current++; for (var i = 0; i ${all.t}'; question = all.ac; answer = all.a; for (var k = 0; k > (choices)
'; quiz.innerHTML = ''; function submit() { if (question.checked === answer && question. length 2) { score += 1; quiz.innerHTML = score; } quizQ();
