title: How to serve up different javascript files by browser width
body: <p>So I want certain Javascript files for certain browser widths.  I know that @media serves up specific CSS per browser width and some devices.
  How would I do something similar for Javascript files, WITHOUT using server side calls?</p>
  
  <p>Is is possible with Javascript to call other Javascript files based on browser width?
  If so, How?</p>
  
  <p>Thanks in advance.</p>
