Don't call us, we'll call you. The 'D' in SOLID is all about inverting control to make your code flexible and testable. Let's wrap up our SOLID series with the Dependency Inversion Principle.

Don't you hate being forced to implement methods you don't need? The 'I' in SOLID is here to fix that. Let's learn how the Interface Segregation Principle helps us create lean, focused code.

If it looks like a duck and quacks like a duck, it should behave like a duck. The 'L' in SOLID is all about making sure your child classes are perfect stand-ins for their parents. Let's dive in.

Want to add new features without breaking old ones? The 'O' in SOLID is here to help. Let's explore the Open-Closed Principle and how to write code that's ready for the future.

Ever seen a class that does everything, including the dishes? Let's talk about the 'S' in SOLID—the Single Responsibility Principle—and why your classes should have only one job.

Why let just anyone mess with your object's data? Learn how getters and setters act like bodyguards for your properties, keeping your code safe, flexible, and bug-free.

When building with code, should you inherit traits like a family tree, or assemble parts like a LEGO set? Let's break down Composition and Inheritance to help you build better, more flexible code.
