Maintainable code is professional code.

Core principles:

• Readability First: Clear variable names and consistent formatting are crucial.
• Single Responsibility: Functions and components should do one thing well.
• Documentation & Comments: Minimal, but meaningful notes prevent confusion.
• DRY (Don’t Repeat Yourself): Reuse code, avoid duplication.

Following these practices not only improves collaboration but also makes your projects easier to scale and debug.
