Reference: https://www.kirupa.com/html5/making_http_requests_js.htm

Code:

				var xhr = new XMLHttpRequest();
				xhr.open('GET', "//ipinfo.io/json", true);
				xhr.send();
				xhr.addEventListener("readystatechange", processRequest, false);

				function processRequest(e) {
					document.getElementById('readyState').innerHTML = JSON.stringify(xhr.readyState);
					document.getElementById('status').innerHTML = JSON.stringify(xhr.status);
					document.getElementById('responseText').innerHTML = JSON.stringify(xhr.responseText.replace(/\n/g,'<br>'));
				}
