Design pattern is a general solution for solving repetitive problems in software design. Here are the pros and cons of design patterns:
Advantages:
Reusability: Design patterns provide a common solution that can be reused across multiple projects and scenarios.
Maintainability: Design patterns provide a structured way to make code easier to understand and maintain.
Extensibility: Design patterns achieve loose coupling by defining interfaces and abstract classes, making the system easier to extend and modify.
Improve code quality: Design patterns enforce the use of best practices, such as object-oriented design principles and design ideas, to improve code quality.
Communication efficiency: Design patterns provide a common language that can speed up the efficiency of communication between team members.
Disadvantages:
Complexity: Design patterns require familiarity with how they work in order to implement them correctly. As a result, beginners can be confused.
Overdesign: Overuse of design patterns can result in code that is overly complex and difficult to understand.
Performance issues: Certain design patterns can cause performance issues, such as using a large number of interfaces and abstract classes.
Not for all scenarios: Design patterns are not a one-size-fits-all solution, so they need to be chosen on a case-by-case basis.
