I can't access to my object's array's values for some reason

I have an object, and I want to log the values array but when I do so, the array is empty. Why is that?

var data = {"values" : []};
   Papa.parse('data.csv', {
    header: true,
    download: true,
    newline: "\n",
    quoteChar : '',
    escapeChar : '',
    chunk: function(results) {
            data.values.push(results.data);
    },
});
console.log(data);
console.log(data.values.length); // 0
console.log(data.values[0]); // undefined

Papa.parse is asynchronous; currently, you're logging the data only after you've send the command to parse the CSV, but the response hasn't come back yet; the callback hasn't triggered. you need to add a complete handler as described in the docs.

Papa.parse('data.csv', {
  header: true,
  download: true,
  newline: "\n",
  quoteChar : '',
  escapeChar : '',
  chunk: function(results) {
    data.values.push(results.data);
  },
  complete: function() {
    console.log('done');
    console.log(data.values[0]);
  }
});
