Scriptaculous
is a powerful extension to the prototype JS library. Prototype +
Scriptaculous provides a functionality set comparable to the other
major toolkits.

The clear focus of Scriptaculous is on visual
effects and low level functionality. It doesn’t support complex widgets
readily and can be cumbersome for complex data manipulation.
