One significant bonus in drastically reducing javascript is improved battery life. > Another thing this article didn't touch on was latency. When I was doing work for vehicles that had poor internet access via satellite every single http call just killed the load (this included fetching css, javascript, etc). I can't stress enough how much better your page can load if you combine as much stuff as possible, even images if you can display them as backgrounds. This, so much this. Particularly with the growing marketplace out side of 1st world countries. Fewer calls of any type are of significant value. Reduce DNS calls, host everything from the same domain where possible, etc. etc. Use sites like https://developers.google.com/speed/pagespeed/insights/ https://developers.google.com/speed/pagespeed/insights/ to help you
