Excerpts and code-snippets from Addy Osmani's Learning Javascript Design Patterns

Categories of Design Pattern:

Creational Design Patterns:

• Creational design patterns focus on handling object creation mechanisms where objects are created in a manner suitable for the situation we're working in. The basic approach to object creation might otherwise lead to added complexity in a project whilst these patterns aim to solve this problem by controlling the creation process.

• Some of the patterns that fall under this category are: Constructor, Factory, Abstract, Prototype, Singleton and Builder.

Structural Design Patterns:

• Structural patterns are concerned with object composition and typically identify simple ways to realize relationships between different objects.

• They help ensure that when one part of a system changes, the entire structure of the system doesn't need to do the same.

• They also assist in recasting parts of the system which don't fit a particular purpose into those that do.

• Patterns that fall under this category include: Decorator, Facade, Flyweight, Adapter and Proxy.

Behavioral Design Patterns:

• Behavioral patterns focus on improving or streamlining the communication between disparate objects in a system.

• Some behavioral patterns include: Iterator, Mediator, Observer and Visitor.
