Over-engineering is a common trap. If a simple if/else block works and stays clean, you do not need to build a complex Strategy or State pattern. If you want to tailor your study plan, let me know: What programming language do you primarily code in? Are you studying for an interview or an active project ? Which specific design pattern gives you the most trouble?
Patterns provide ready-made solutions, reducing the time spent on designing solutions from scratch.
GitHub is an excellent platform for exploring and learning design patterns, with numerous open-source projects and repositories available. Here are some popular GitHub resources:
Do not rush. Spend a few days understanding a single pattern, like the Strategy pattern. Learn its mechanics, its flaws, and its strengths. dive into design patterns pdf github
: Each pattern follows a consistent flow: Problem →right arrow →right arrow →right arrow Pseudocode →right arrow Applicability →right arrow Pros/Cons. Pros and Cons Pros Cons
If you happen to be a Python developer, there is a famous free GitHub PDF.
"Beautiful, isn't it?" a voice said.
Chain of Responsibility: Passes a request along a chain of handlers. Upon receiving a request, each handler decides either to process the request or to pass it to the next handler in the chain.Command: Encapsulates a request as an object, thereby letting you parameterize clients with different requests, queue or log requests, and support undoable operations.Interpreter: Provides a way to evaluate language grammar or expression for a particular language.Iterator: Provides a way to access the elements of an aggregate object sequentially without exposing its underlying representation.Mediator: Defines an object that encapsulates how a set of objects interact, promoting loose coupling by keeping objects from referring to each other explicitly.Memento: Captures and externalizes an object's internal state so that the object can be restored to this state later without violating encapsulation.Observer: Defines a one-to-many dependency between objects so that when one object changes state, all its dependents are notified and updated automatically.State: Allows an object to alter its behavior when its internal state changes. The object will appear to change its class.Strategy: Defines a family of algorithms, encapsulates each one, and makes them interchangeable, letting the algorithm vary independently from the clients that use it.Template Method: Defines the skeleton of an algorithm in an operation, deferring some steps to subclasses.Visitor: Represents an operation to be performed on the elements of an object structure, letting you define a new operation without changing the classes of the elements on which it operates. Leveraging GitHub and PDF Resources
Explain how to assemble objects and classes into larger structures while keeping them flexible and efficient (e.g., Adapter, Decorator, Facade).
