As a junior backend developer fresh out of university, debugging felt like staring into the abyss. But after breaking — and fixing — enough code, I've learned to treat it like detective work.
Early on, I'd panic at errors. Over time, I learned bugs are normal, even for seniors. Now I treat them as clues. My go-to tools: console.log() was my first best friend, breakpoints in VS Code were a game-changer, and Postman became essential for API debugging — especially when something "works locally" but breaks everywhere else.
My debugging workflow: first, reproduce the bug — if you can't replicate it, you can't fix it. Then simplify by commenting out large chunks and testing smaller pieces. Finally, rubber ducking — I explain my bugs out loud to an actual rubber duck on my desk. It works more than it should.
The hardest bug I ever fixed was a memory leak in a Node.js app that caused random crashes. I traced it back to improper event listeners. It taught me to always clean up after processes, and to look beyond the obvious when something behaves unpredictably.
