Writing clean and maintainable code is what separates junior developers from senior engineers. It’s not just about making code work—but making it easy to understand, change, and extend.

Core principles:

1. Meaningful Naming
   • Use descriptive names: calculate_total() > calc() or ct().
   • Avoid abbreviations and cryptic variables.
2. Single Responsibility
   • Each function, module, or class should do one thing and do it well.
3. Keep It DRY (Don’t Repeat Yourself)
   • Abstract repeated code into reusable functions or components.
4. Comment When Necessary
   • Avoid obvious comments—focus on the “why” instead of “what”.
5. Consistent Formatting
   • Use code formatters like Prettier, Black, or clang-format.
   • Stick to team or community style guides.
6. Modular Design
   • Split code into logical files and folders.
   • Encapsulate related logic into reusable modules or classes.
7. Write Tests
   • Unit and integration tests ensure long-term code stability.
   • TDD can help you stay focused and write better interfaces.
8. Refactor Regularly
   • Treat messy code like debt—clean as you go.

Clean code is readable, testable, and extensible. Prioritize future maintainers (including yourself), and you’ll write code that lasts.
