Tiny baby ajax

function ajax (url = "/", resType = 'text') {
  return new Promise (function (resolve, reject) {
    var req = new XMLHttpRequest();
    req.onreadystatechange = function () {
      if (req.readyState === 4) {
        if (req.status >= 400 && req.status < 600) {
          reject("HTTP Error " + req.status + ": " + req.statusText);
        } else if (req.status >= 200 && req.status < 400) {
          resolve(req.response);
        }
      }
    };
    req.open("GET", url);
    req.responseType = resType;
    req.setRequestHeader('X-Requested-With', 'XMLHttpRequest');
    req.send();
  });
}

ajax("/url", "json").then(function (response) {

  console.log(response.prop);

});

— +1. But this condition && req.status < 600, is really necesary?

— Just seem too paranoid, but I think it's ok 😂

— Other Admins, DO NOT delete this! Yes it is spam (because no one requested and is almost not related to js) but Fazal is the admin of this group. So let's allow this post this time.

— Right

— My apologies. I had sent request to few admins who were common admins for multiple groups. Seems this group is not owned by them. Thank you for allowing it for the timebeing.

— Other programming group admins think too high of themselves as if they are Mark Zuckerberg or Larry Page. Admins of this group seem cooler though like a JS Dev should be.

— It's easier to be a "cool" admin in a small 100 person group with well-behaved people :)
