Is it possible to find out the headers when loading a JS script?

Question

JavaScript

var script = document.createElement('script');
script.src = "https://code.jquery.com/jquery.js";
document.documentElement.appendChild(script);

I ship like this. I'm interested to know the response headers of the script being loaded:
date:Sun, 26 Feb 2017 00:00:00 GMT
etag:"хххх"
status:200
Is there any way to get this data.
