HTML Preparation code:

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.4.1/jquery.min.js"><script>

Script Preparation code:

function showResult(data) {
    console.log(data);
}
var newUrl = "https://www.googleapis.com/discovery/v1/apis";

Tests:

Native XHR
var xhr = new XMLHttpRequest(); xhr.open("GET", newUrl, true); xhr.onreadystatechange = function() { if (xhr.readyState === 4) { showResult(xhr); } } xhr.send();
Native XHR 2
var xhr = new XMLHttpRequest(); xhr.onload = showResult; xhr.open("GET", newUrl, true); xhr.send();
Native fetch.then
var request = fetch(newUrl).then(showResult);
jQuery Ajax
var request = $.ajax({ type: "GET", url: newUrl, success: showResult, data: null });
jQuery Ajax (Async)
var request = $.ajax({ type: "GET", async: true, url: newUrl, success: showResult, data: null });
jQuery Get
var request = $.get(newUrl, showResult);
jQuery Get 2
var request = $.get(newUrl).done(showResult);
