How do I convert jQuery AJAX code to vanilla JavaScript?

Question

I have an AJAX script in jQuery that I am trying to convert to vanilla Javascript. I Can't seem to convert this. How would I convert this to vanilla JavaScript?

$.ajax({
  url: 'csv_data.csv',
  dataType: 'text',
}).done(successFunction);

$('body').append(table);

That is plain javascript. Do you mean you don't want to use jQuery? — Mark, Jul 29 '18 at 16:34
fetch(url, request).then(function(respose) { successFunction(response)}) — Egor Egorov, Jul 29 '18 at 16:35

Using XMLHttpRequest

var r = new XMLHttpRequest();
r.open('GET', 'csv_data.csv');
r.onreadystatechange = function () {
    if (r.readyState != 4 || r.status != 200) return;
    successFunction(r.responseText);
};
r.send();

Haven't tested it.

You can use fetch API for Ajax request.

fetch("csv_data.csv", { headers: { "Content-Type": "text/csv" } })
  .then(function(response) {
    return response.txt();
  })
  .then(successFunction);
document.body.appendChild(table);
