even simpler async/await ajax

ajax-promise.js

var pbj = {};
pbj.xhr = url => {
  return new Promise((resolve, reject) => {
    const xhr = new XMLHttpRequest();
    xhr.open('GET', 'https://reqres.in' + url);
    xhr.onload = () => resolve(xhr.response);
    xhr.onerror = () => reject(xhr.status);
    xhr.send();
  })
};
pbj.load = async function (url) {
  return await pbj.xhr(url);
};
pbj.load('/api/users?delay=3').then(response => {
  console.log(response);
});
