Answer 1

In your script

 var width = (window.innerWidth > 0) ? window.innerWidth : screen.width;
 var head = document.getElementsByTagName('head').item(0);
 if(width > 950){
       var script = document.createElement("script");
       script.type = "text/javascript";
       script.src = "http://www.domain.com/js/jquery.min.js";
       head.appendChild(script);
    }
