Make request using XMLHttpRequest

var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function(r) {
  if ( xhr.readyState == 4 ) {
    console.log(xhr.responseText);
  }
});
xhr.open('GET', 'https://example.org/');
xhr.send();

• new XMLHttpRequest - create XMLHttpRequest object
• onreadystatechange - handle request processing
• example.org/ - send request to this URL
• readyState == 4 - request has been executed
• console.log(xhr.responseText) - place your code to process response here
• 'GET' - use GET method for request
• xhr.send() - send the request
