    Making Your Code Endure Beyond Your Tenure

    Do you consider your code's fate when you leave a project? In the fast-paced world of software development, this critical aspect is often ignored. Think about the long-term impact of your work, not just solving immediate issues.

    As a developer, you will eventually inherit a project. The existing code shows how the original developer thought. It shows how they faced challenges and solved problems. Your job is to understand and build upon this existing code.

    Donald Knuth said, "The best programs are written so that computing machines can perform them quickly and so that human beings can understand them clearly."

    To have a maintainable codebase, you need good documentation and solid testing. The documentation should explain what the code does. It should also explain the thinking behind it, especially for complex parts. This helps future developers understand both the 'how' and the 'why.' Documentation includes not only the README files but also the inline comments in the source code.

    Next, document your development choices, such as technology and structure. Explain why you made these choices to guide future developers. This helps make the project consistent and adaptable.

    Finally, document troubleshooting. Each solved problem and fixed bug helps others who encounter similar issues. This makes the codebase stronger and more flexible.

    Writing code is about setting the stage for future success. A well-documented, tested, and maintainable codebase is a technical asset. It is the cornerstone of a lasting business. The value of our work lies in its accessibility and usability by all developers, present and future. This ensures that a project isn't reliant on a small group or an individual.

    By the way, I have a book about Pull Requests Best Practices. Check it out!
