Project Guidelines

Favor Class Composition Over Inheritance

• Reduced Coupling: Using composition over inheritance reduces coupling between classes, making the codebase easier to maintain and understand.
• Explicit Dependencies: It's clear what dependencies are required by a class.
• Increased Flexibility: Composition allows dynamic behavior swapping, unlike inheritance which is static.
• Ease of Testing: Testing composed objects is often simpler because you can isolate components.

# Good: Using Composition
