Prototype Tutorial: Painless JavaScript Using Prototype

Prototype is an object oriented JavaScript [1] library (written by Sam Stephenson and friends) that makes JavaScript fun. So it says on the site [2], anyway.

However, Prototype can be used independently of Rails to aid the coding of many JavaScript doodads and Web 2.0 thingy wangles.
