These libraries can be dropped into any project to provide useful additional functionality.

Recurly.js

Allows you to embed secure, PCI compliant order forms. The library performs in-line validation, real-time total calculations, and gracefully handles errors. Your customer stays on your website while their billing information is securely sent to Recurly for approval.

YepNope.js

By now you've built up quite a list of Javascript resources to load. A good idea at this point would be to use a script loader. YepNope is an asynchronous conditional resource loader that's super-fast, and allows you to load only the scripts that your users need.

Plus, 3 jQuery plugins you should try

Sure, there's a jQuery plugin for everything these days, but these three in particular struck me as incredibly cool ideas for enhancing UI.

Twinkle

Draw your visitor's attention to special parts of your website.

Fracs

Determine the visible fractions of an element. jQuery.fracs determines the fraction of an HTML element that is currently in the viewport, as well as the fraction it takes of the complete viewport and the fraction of the area that might possibly be visible.

Scrollorama.js

Seen that famous Nike site? This plugin makes it easy to add all manner of parallax and other scrolling effects to your page.
