Why do we need clean code?
Bro sis, have you ever felt frustrated when you see your own code or your friend's code that is super complicated? It's like watching a Korean drama without subtitles—totally confusing! Well, clean code is like a cool subtitle that makes everyone understand the storyline. Come on, let's talk about why you should bother writing clean code!
1. So You Don't Get Lost: Readability is 🔑
Imagine going into a new meatball shop, the menu is not clear, the names of the meatballs are different. Are you mad? It's the same in the code. The variable names a
, b
, c
make you play around like you are dancing alone.
// ✗ Regret reading this function f(a, b) { return a * b + 42 - c; } // ✓ Easy to read function calculateFinalScore(baseScore, multiplier, bonus) { return baseScore * multiplier + bonus; }

2. Not Emotional During Revisions: Maintainability FTW
You're working on a new feature, but suddenly a bug appears. If your code is messy, fixing bugs takes time, like waiting in line to buy rare items.
- Clean code: modular, small functions, easy to replace
- Spaghetti code: hang around in every corner, you become a dirty dish cleaner
3. Teamwork Made Fun: Collaboration 🎉
Imagine coding alone in a cave, then suddenly invited to a team. If your code is unclear, your friends will complain: "Bro, what's the point of this?". But if you write clean code:
- Self-explanatory documentation via function/variable names
- Style consistency: everyone uses the same pattern
- Fewer merge conflicts when collaborating in Git
4. Debugging doesn't use drama: Fewer Headaches 🧠💊
Clean code is like code that has instructions. You just click, trace, fix. No need to be Sherlock Holmes, hunting for clues.
// Add clear logging for easy debugging function fetchUserData(userId) { console.log(`[DEBUG] fetchUserData called with userId=${userId}`); // ... call API }
