Design patterns help to provide structure and organization to a software development project. Applying them can help make the development process more efficient and produce better results.
The simplest way to apply design patterns is to identify the parts of your program that could benefit from a more organized approach, and apply one of the common design patterns to that section of the code. For example, if you are developing a graphical user interface (GUI) and you want to handle user input events in an object-oriented manner, you could consider using the Model-View-Controller (MVC) pattern.
Design patterns also provide guidance on how to organize and structure your code. In this regard, the most popular design patterns are the Model-View-Controller (MVC), Object-Oriented (OO), and Factory patterns.
Model-View-Controller makes it easier to create a GUI and separate the core logic from the user-facing elements, which allows for faster development and better extensibility. Object-Oriented helps you to better organize your code by making sure that the same type of entities are stored and handled together, and implementing abstractions (like interfaces) to make sure that details of a specific feature or function are kept in isolation from the rest of the system. Finally, the Factory pattern is a great way to create objects without having to repeat code, and to make sure that the right properties and methods are assigned to your objects.
In addition to using the more common design patterns, you can also create your own custom design patterns, if needed. However, it is important to remember that the goal of design patterns is to simplify the development process and make sure that all parts of your code are consistent, organized, and readable, so the fewest number of patterns possible should be used.
