This project is a result of the reading group about design patterns. Starting the 6th of june, every week there will be a meetup and a new design pattern will be added to this repo.
The Strategy Pattern defines a family of algorithms, encapsulates each one, and makes them interchangeable. Strategy lets the algorithm vary independently from clients that use it.

The Observer Pattern defines a one-to-many dependency between objects so that when one object changes state, all of its dependents are notified and updated automatically.

The Decorator Pattern attaches additional responsibilities to an object dynamically. Decorators provide a flexible alternative to subclassing for extending functionality.

The Factory Method Pattern: defines an interface for creating an object, but lets subclasses decide which class to instantiate. Factory Method lets a class defer instantiation to subclasses.
The Abstract Factory Pattern provides an interface for creating families of related or dependent objects without specifying their concrete classes.

The Singleton Pattern ensures a class has only one instance, and provides a global point of access to it.

The Command Pattern encapsulates a request as an object, thereby letting you parameterize other objects with different requests, queue or log requests, and support undoable operations.

The Adapter Pattern converts the interface of a class into another interface clients expect. Lets classes work together that couldn't otherwise because of incompatible interfaces.
The Facade Pattern provides a minified interface to a set of interfaces in a subsystem. Facade defines a higher-level interface that makes the subsystem easier to use.

The Template Method Pattern defines the skeleton of an algorithm in a method, deferring some steps to subclasses. Template Method lets the subclasses redefine certain steps of an algorithm without changing the algorithm's structure.

The Iterator Pattern provides a way to access the elements of an aggregate object sequentially without expoing its underlying representation.
The Composite Pattern allows you to compose objects into tree structures to represent part-whole hierarchies. Composite lets clients treat individual objects and compositions of objects uniformly.

The State Pattern allows an object to alter its behavior when its internal state changes. The object will appear to change its class.

The Proxy Pattern provides a surrogate or placeholder for another object to control access to it.

A Compound Pattern combines two or more patterns into a solution that solves a recurring or general problem.
