Design pattern: Strategy

Description: "Define a family of algorithms, encapsulate each one, and make them interchangeable. Strategy lets the algorithm vary independently of from clients that use it."

This pattern can be used with both classes and prototypes.

The sample implementation uses prototypes and dynamic object predicates to allow the strategy to be changed dynamically at runtime.
