Object-Oriented Principles

Covers the key ideas behind object-oriented programming like SOLID, encapsulation, and choosing between inheritance and composition to help you write flexible, maintainable code.

• SOLID Principles: The Foundation of Good Code

  The SOLID principles are five guidelines for writing object-oriented code that is easy to understand, change, and maintain.

• Encapsulation: Why Protecting Data Matters

  Encapsulation means keeping an object's data and behaviour together, so you can protect internal details and prevent accidental changes from outside.

• Law of Demeter: Only Talk to Your Friends

  The Law of Demeter encourages code that only communicates with closely related objects, making your software easier to change and less prone to errors.

• Loose vs Tight Coupling: Why Relationships Matter in Code

  This article compares loose and tight coupling, showing why loosely connected code is easier to update, test, and reuse in bigger projects.

• Composition over Inheritance – When to Pick Each

  This article explains why using composition can make your code more flexible than inheritance, and how to choose the right approach for your design.
