title: Is it possible to load in a local version of a JavaScript file instead of the server version?
body: <p>Just had a quick question to throw out and see if there was a solution for this...</p>
  
  <p>Let's pretend I have no access to the server.
  I load up a webpage and find out that they have a Javascript file loading from a subfolder (let's say /scripts/js/some.js)</p>
  
  <p>Now, I want to make changes to this file locally and test it against the whole site without downloading the entire site to a local folder.</p>
  
  <p>Does anyone know of a way I can override the loading of that remote js file in favor of a local/edited copy of it?</p>
