jQuery as we know comes loaded with most websites today. However, if there is a case when you’d like to run some experiments on website using jQuery but it isn’t being load by default, you can run following command
var jqry = document.createElement('script');
jqry.src = "[https://code.jquery.com/jquery-3.3.1.min.js";](https://code.jquery.com/jquery-3.3.1.min.js)
document.getElementsByTagName('head')\[0\].appendChild(jqry);
jQuery.noConflict();
