LightningJS: safe, fast, and asynchronous third-party Javascript Why care about third-party Javascript embedding? Over the last five years or so, embedding Javascript code has become the norm. Much of this code is delivered by third-party services like Google Analytics and others.

Services like Facebook, Twitter and Disqus, programmable widgets like Google Maps, and even invisible scripts like Google Analytics, KissMetrics and our own Errorception give you ways to integrate their services with your website.
