Hello who can help me with this? I have a json and I parse it, after that for each item i need to create an array

This is my json:

    content: "content0"
    comment: "comment0"
  1: Object
    title: "title1"

    comment: "comment1"

I have a function

var mystockinfo = [];

function uploadSomething(data){
  var myjsonparse = JSON.parse(data.div);
  for (var i = 0; i < myjsonparse.length;){
        mystockinfo[i][0] = myjsonparse[i].title;
        mystockinfo[i][1] = myjsonparse[i].content;
        mystockinfo[i][2] = myjsonparse[i].comment;

}

console.log(mystockinfo);

I need to have

[ 0 => [title0, content0, comment0], 1 => [title1, content1, comment1]]

Using .map() is an easy way to loop through the array and transforming it into the nested arrays you need.

var obj = [{
  title: "title0",
  content: "content0",
  comment: "comment0"
}, {
  title: "title1",
  content: "content1",
  comment: "comment1"
}];

var updated = obj.map(function(ind) {
  return [ind.title, ind.content, ind.comment];
});

console.log(updated);

</div>
