The Strategy pattern is a behavioral design pattern that enables selecting an algorithm's behavior at runtime. It defines a family of algorithms, encapsulates each one, and makes them interchangeable, promoting clean and maintainable software architecture.
By implementing the Strategy pattern, developers can add new behavior organically without modifying existing code, effectively adhering to the Open/Closed Principle and ensuring that code remains extensible and maintainable over time.
Using simple if-else or when constructs can lead to code that is hard to read and maintain, directly conflicting with object-oriented principles and complicating future extensions.
The problem with using if-else is that it quickly escalates into complex code that is difficult to manage. As new screens are added, developers are forced to modify existing implementations, thus violating SOLID principles.
