In this video, we explore how to replace long switch or if/else statements with Dependency Injection (DI) to write cleaner, more maintainable code.
You’ll learn:
✅ Why functions with switch(if/else) statements can violate the Open/Closed Principle (OCP)
✅ How to refactor to use Factories with Strategy patterns
✅ How to dynamically register behaviors without touching core logic
✅ The difference between the bad approach (modifying existing code) and the good approach (extending)
By the end, you’ll know how to design code that’s flexible, testable, and future-proof — and you’ll see a real-world example with tax and pricing policies.
