(https://stfalconcom.medium.com/software-design-patterns-every-dev-have-to-know-efb88accf446)
Patterns are reusable solutions to common design problems, resulting in a smoother, more efficient development process. They serve as blueprints for building better software structures. These are some of the most popular patterns:
- Abstract Factory: Family Creator – Makes groups of related items.
- Builder: Lego Master – Builds objects step by step, keeping creation and appearance separate.
- Prototype: Clone Maker – Creates copies of fully prepared examples.
- Singleton: One and Only – A special class with just one instance.
- Adapter: Universal Plug – Connects things with different interfaces.
- Bridge: Function Connector – Links how an object works to what it does.
- Composite: Tree Builder – Forms tree-like structures of simple and complex parts.
- Decorator: Customizer – Adds features to objects without changing their core.
- Facade: One-Stop-Shop – Represents a whole system with a single, simplified interface.
- Flyweight: Space Saver – Shares small, reusable items efficiently.
- Proxy: Stand-In Actor – Represents another object, controlling access or actions.
- Chain of Responsibility: Request Relay – Passes a request through a chain of objects until handled.
- Command: Task Wrapper – Turns a request into an object, ready for action.
- Iterator: Collection Explorer – Accesses elements in a collection one by one.
- Mediator: Communication Hub – Simplifies interactions between different classes.
- Memento: Time Capsule – Captures and restores an object’s state.
- Observer: News Broadcaster – Notifies classes about changes in other objects.
- Visitor: Skillful Guest – Adds new operations to a class without altering it
