What is the fastest way to work with ajax request?
<p>I am a little bit confused about what is the fastest and the friendly way with the server to request POST or GET from server by AJAX, is it jQuery (<code>$.load()</code>, <code>$.get()</code>, <code>$.post()</code>, <code>$.ajax()</code>) or Javascript like XMLHttpRequest? </p>

<p>I need to make a function or class to use in my project to call request from server via AJAX, but I don't know what is the faster and more friendly with the server jQuery or Javascript.</p>
