What development principles, besides SOLID, do you know and can describe?

In addition to SOLID, there are other important development principles that help create quality and maintainable code:

• DRY (Don't Repeat Yourself) — avoid code duplication so that changes in logic require edits in only one place.
• KISS (Keep It Simple, Stupid) — strive for simplicity in solutions, avoiding unnecessary complexity.
• YAGNI (You Aren't Gonna Need It) — do not implement functionality in advance if it is not needed right now.
• Law of Demeter (Principle of Least Knowledge) — modules should interact only with closely related objects, minimizing dependencies.
• Composition over Inheritance — prefer object composition over inheritance for greater flexibility.

These principles help write cleaner, more understandable, and easily maintainable code.
