OOPs

Introduction Ever stared at a massive class file with hundreds of lines of code and thought, “What is this thing even supposed to do?” I sure have. That confusion usually points to problems with cohesion and coupling, two concepts that might sound academic but actually make the difference between code you want to work with and code you want to run away from. Let’s talk about these two fundamental ideas that can transform your code from a tangled mess into something you’re actually proud of. ...

Introduction If you’ve ever been in a job interview for a software developer position, chances are you’ve been asked to explain the difference between DIP, DI, and IoC. I know I have, and the first time I was asked, I definitely stumbled through my answer! These three terms, Dependency Inversion Principle, Dependency Injection, and Inversion of Control, sound awfully similar and are often used interchangeably (incorrectly) by developers. But they’re actually distinct concepts that play different roles in helping us write better code. ...

Introduction If you’ve been coding for a while, you’ve probably heard of SOLID. It’s a set of five design principles that Robert C. Martin (better known as “Uncle Bob”) came up with back in the early 2000s. Since then, these ideas have become pretty much essential knowledge for anyone writing object-oriented code. But SOLID isn’t just another tech buzzword to memorize for interviews. These are practical ideas that actually help you write better code. I’ve found that following these principles helps me avoid creating those messy, brittle codebases that become a nightmare to change later on. ...

Introduction to Object-Oriented Programming Ever wondered why most modern programming languages are object-oriented? It’s not just a trend; OOP completely changed how we think about building software. Object-Oriented Programming (or OOP, as we’ll call it) burst onto the scene in the 1990s and turned traditional programming on its head. Before OOP came along, most developers wrote procedural code, essentially a series of steps for the computer to follow, like a cooking recipe. While that worked for simpler programs, it became unwieldy as software grew more complex. ...
