Understanding SOLID Principles (Without Falling Asleep)

Ever read about SOLID and felt your eyelids droop halfway through the “S”? Let’s fix that. Whether you're debugging spaghetti code at 2 AM or trying to prevent future you from rage-quitting, SOLID principles are here to help. But let's be honest—they’re often taught in the driest way possible. In this article, I’ll walk you through the SOLID principles using TypeScript, real-world analogies, and some much-needed humor. No jargon. No hand-waving. Just clean, readable code examples you’ll understand and remember. Why SOLID Matters (And Why It’s Often Boring) SOLID is a set of five design principles that make your code: Easier to maintain Easier to test Easier to extend without breaking things Yet, most explanations feel like they were written by a robot for other robots. That ends now. Let’s break each principle down like we're refactoring your first bootcamp project—one bug at a time.
