example of my version of the beginning stages of the JavaScript for a quiz app

script.js

var output = document.getElementById('output');
var myData = '[{"question":"What color is an apple?","answers":["Blue","Red","Purple"],"correct":1},{"question":"What color is grass?","answers":["Green","Red","Purple"],"correct":0}]'
var myObj = JSON.parse(myData);
for (var i in myObj) {
  output.innerHTML += myObj[i].question + '? <br>';
}
output.innerHTML = myObj[0].question;
console.log(myObj);
