CloudFlare offers a service called Rocketscript, which compresses, concatenates, and defers any JavaScript on your web pages. On some websites, it can make a significant difference to the apparent page load time, because it waits until the web browser has loaded the page before it loads and executes scripts. Of course, that sometimes means it breaks things! Fortunately, CloudFlare offers a way to avoid that, and it's possible to use it on your WordPress plugin scripts.
