“Clean code always looks like it was written by someone who cares.” — Robert C. Martin
-GoodReads-
Clean code isn’t a buzzword – it’s a practice that can change how you write, maintain, and share your code for years to come. Whether you’re a seasoned developer or a self-taught freelancer piecing together client sites in WordPress, the phrase “clean code” gets thrown around a lot. But what does it actually mean? And why should it matter to you, especially if your code technically works just fine?
Let’s break it down.
Clean Code Isn’t Just About Syntax
At its core, clean code isn’t about style preferences. It’s about clarity. It’s code that’s easy to read, understand, and maintain. Think of it as writing a love letter to your future self—or the poor soul who has to update your project six months from now.
It’s not enough that it runs. It needs to make sense. And when it does, everyone wins.
What Clean Code Looks Like
Clean code is:
- Well-named: Functions, variables, and classes have names that explain what they do.
- Consistent: Formatting, indentation, and naming conventions follow predictable patterns.
- Minimal: No unnecessary repetition or clutter. Every line earns its place.
- Modular: Logic is broken down into reusable, single-purpose functions or components.
- Comment-light: Comments are helpful, not band-aids for confusing logic. Ideally, the code explains itself.
Clean code is kind to those who come after you—including future you.
Why You Should Care
- You’ll move faster. Messy code may feel faster to write, but it’s slower to debug and update. Clean code saves time in the long run—even when you’re working solo.
- It’s your professional reputation. If you’re building client sites (like I do), your codebase is part of your brand. A developer who leaves behind tidy, understandable files gets asked back. The one who leaves chaos? Not so much.
- Future you will thank you. You think you’ll remember what that “function123” does three months from now? You won’t. Clean code spares you the detective work.
- It scales better. Whether you’re bringing in collaborators or revising an old project, clean code makes it easier to build on what’s already there.
Clean code is especially valuable when working on WordPress projects, where themes, plugins, and client edits can pile up fast. Having a readable, modular structure makes those tweaks safer, faster, and more reliable—whether you’re handling it yourself or passing it off to someone else.
How to Start Writing Cleaner Code
You don’t need to memorize a giant manual. Start simple:
- Use clear, descriptive names
- Remove unused code and comments
- Break big functions into smaller, focused ones
- Stick to consistent indentation and spacing
- Don’t repeat yourself (DRY principle)
And when in doubt, refactor. Clean code is rarely written on the first try—it’s shaped through iteration.
Writing clean code also makes collaboration easier. If you ever hand off a project, hire a subcontractor, or open-source something, your code will speak for itself. You won’t need to explain every function, and your collaborators will spend less time guessing – and more time building. Even in small personal projects, writing clean code builds discipline. It trains you to think clearly, solve problems efficiently, and build things that last – skills that apply across every tool, stack, or platform.
Bottom Line
Writing clean code isn’t a luxury. It’s a discipline—and one of the best investments you can make in your development career or freelance business. Whether you’re writing a WordPress function, a JavaScript loop, or just tweaking some CSS, the mindset matters:
Make it work. Make it clear. Then make it better.
