Writing Clean and Understandable Code: Your Future Self Will Thank You
Ever opened code you wrote two weeks ago and wondered, "Who wrote this?"—only to realize it was you? Yep. We've all been there.
Welcome to the messy world of spaghetti code—the unintentional nightmare most developers walk into, especially when we're in a rush, chasing deadlines, or just feeling lazy (we've all said "I'll clean it later"). But here’s the thing: clean code isn't just for teams, it's a gift to your future self.
Let’s explore why cleanliness, orderliness, and structure in your code are non-negotiable, and how to achieve it in real life.
Why Does Clean Code Even Matter?
1. Readability Saves Time
When code is clean and structured, it tells a story. It’s easier to read, easier to fix, and far easier to extend. That means less time debugging and more time building.
2. Easier Collaboration
Your team will love you—or at least not hate you—when you write clean code. Well-structured code with proper naming and comments is like good manners for developers.
3. Reduces Bugs and Technical Debt
Messy code leads to missed logic, duplicate code, and sneaky bugs. Clean code = cleaner logic = fewer bugs. Simple math.
4. Future-Proofs Your Projects
Codebases grow. Clean structure helps scale them. Think of it like arranging your room before a party. Guests (a.k.a. new features and new developers) won't trip over your laundry.
What Makes Code "Clean"?
1. Clear Naming Conventions
Variable and function names should be descriptive. calculateTotal() > calcT().
2. Proper Indentation & Spacing
Tabs, spaces, line breaks—they matter more than you think.
3. Comments Where Necessary
Don’t narrate the obvious, but leave helpful breadcrumbs. Think future-you or your confused teammate.
4. DRY Principle
"Don’t Repeat Yourself." If you copy-paste logic, stop and refactor it.
5. Logical Folder and File Structure
Especially in large projects, organizing files logically is gold. Keep related stuff together.
Tools That Help You Write Clean Code
In Visual Studio Code
- Prettier – Auto formats your code.
- ESLint – Catches syntax and style errors.
- Comment Anchors – Lets you structure your code with tags like
TODO:andFIXME:. - GitLens – Track changes and authors to avoid blame games.
Other Useful Tools
- SonarLint – For deep code analysis.
- EditorConfig – Helps maintain consistent coding styles across editors.
- JSDoc or DocBlocks – For writing comments that actually matter.
A Quick Scenario
You open your old project and see a function called doSomething() with 50 lines of logic and zero comments.
Your brain: "What... why?!"
Moral of the story: Clean code isn’t just aesthetics, it’s peace of mind.
Good Practices to Start Today
- Refactor after adding new features.
- Use
TODO:orNOTE:comments to mark future changes. - Keep functions short and single-purpose.
- Use version control (Git) wisely and commit with meaningful messages.
- Always run a linter before pushing code.
Conclusion: Code Like a Pro, Not Like a Caveman
Clean code is more than a best practice—it’s a habit, a courtesy, and a future-proof strategy. So next time you code, write like someone else will read it. Because trust me, that “someone” might just be you on a Monday morning with no caffeine.
Start small. Clean one file. Refactor one function. Add one comment. It adds up.
