• Improved maintainability: Clean code is easier to maintain. As projects grow, maintaining clean code becomes most important for ongoing development. since our code is already structured, it will be easy to add new features or change existing ones without breaking everything.
• Better documentation: Clean code should be self-explanatory, it often reduces the need for extra comments. Good naming and structure act as documentation itself, making the code easier to understand without additional explanations needed.
• Long-term success: Projects grow over time, and clean code does supports long-term success. It ensures that your code-base can adapt new changes and requirements .
• Increases job opportunities: In todays job market, companies look for developers who write clean, maintainable code. Demonstrating these skill in your personal project can lead to better job chances and career advancement.
