This is fairly old. It goes with John Resig's book "Secrets of the JavaScript Ninja Released" which was released at the beginning of 2013 [1]. I remember seeing this site up well before that. He started the book in 2008.

If you can work your way through this tutorial you'll gain a decent grasp of ES5 prototypes and functions.
