JavaScript Hits #1 On GitHub
JavaScript is now the most popular language on GitHub. It only seems natural considering the popularity of web applications — have you worked on a web application that doesn’t use JavaScript somewhere? But it’s not just projects like jQuery at the top, key server-side projects are in the most watched overall category, like Express.
BitmapData.js

BitmapData.js (GitHub: BitmapData.js) by Peter Nitsch is a Canvas implementation of the AS3 BitmapData class. I haven’t used much AS3 myself, but the examples look pretty good:
This is another useful library for ActionScript developers who are moving into Canvas-based development.
WebKit Clock

WebKit Clock by Ono Takehiko uses no images (apart from the social network sharing buttons) to generate an amazing world clock. There are delicious animations for switching between cities, and an Apple Dashboard-style clock. It uses a lot of box-shadow, border-radius, and a Canvas for the map.
I was particularly impressed with the map animation. If you’re looking for more inspiration, the author has dozens of other interesting projects on onotakehiko.com.
