Full-featured shooter in 20k of Javascript code!
KhanAcademy showed an example Javascript code on how to write a full-featured space-shooter written in just 1500 lines of code (20k of pure Javascript code after minification).
No matter, whether you are a JS-minification freak or just want to introduce some space shooter on your website to enjoy your visitors — this is certainly worth seeing. Of course, KhanAcademy offers a lot of more nifty Javascript examples.
