Writing code that works is only half the job. Writing clean and smart code is what sets great developers apart — especially when working in a team or maintaining code over time.
Here are 7 habits that make your code cleaner, smarter, and easier to work with:
-
Name Things Clearly
Use meaningful variable and function names. Say goodbye to x, y, z — and hello to userEmail, formatDate(), and calculateTotal(). -
Keep Functions Short
One function = one purpose. Avoid long, multi-purpose functions. Keep logic bite-sized and reusable. -
Comment Why, Not What
Don’t state the obvious. Instead of // add 1 to counter, write // accounts for zero-based indexing. Explain your intention. -
Use Consistent Formatting
Indentation, spacing, and bracket style should be uniform. Use a formatter (like Prettier) or linter (like ESLint) to keep it clean. -
Avoid Hardcoding
Replace magic numbers and strings with constants. It improves readability and reduces bugs. -
Refactor Ruthlessly
If something feels clunky or repetitive, refactor. DRY: Don’t Repeat Yourself. Less code = fewer bugs. -
Think in Modules
Structure your code by responsibility. Group related functions and separate concerns. This makes testing and scaling easier.
Bonus:
Use version control (Git!), write clear commit messages, and review your own pull requests before hitting submit.
