Google Adsense multiple ads same page use same external JS multiple times?

JavaScript
1

So I figured I could just add the common external script to the bottom of the page. No ads show then. I havnt tested one external script directly after multiple adsense blocks. How is this done? Seems very unnessesasry, not to mention massive page bloat, to add multiple instances of the same script. Solution??

Thanks!

What you all just blindly put all the js on your page and pay no mind to the 2 second page load decrease?
