Why Do Developers Sometimes Leave Unprofessional Comments in Their Code?

Developers are human, and like any other human, they experience frustration, humor, and other emotions that can influence their work. In the context of coding, developers may leave unprofessional comments in their code for various reasons. Here, we will delve into the reasons behind these comments, explore how they can impact code maintainability, and discuss the importance of maintaining a professional tone.

Frustration and Humor

One common reason for leaving unprofessional comments is frustration with complex problems or challenges during coding. Developers may use humor to cope with these situations, which can serve as a personal vent or a light-hearted way to break the monotony of coding. However, such comments can also lead to misunderstandings or a lack of clarity for future developers working on the code.

Lack of Awareness

Not all developers recognize the importance of professionalism in comments. They may not consider the fact that their comments could be read by others or become part of a larger codebase. This lack of awareness can contribute to unprofessional comments becoming a recurring issue within a team.

Team Culture

Team culture plays a significant role in the prevalence of unprofessional comments in code. In some teams, informal communication and humor are encouraged, leading to a more relaxed approach to commenting. This can create a culture where unprofessional comments are more common, potentially diluting the professionalism of the overall codebase.

Time Constraints

Fast-paced environments often prioritize getting the code working over maintaining professionalism in comments. Developers might leave quick informal notes as placeholders to revisit later. While these comments serve a practical purpose, they can become a maintenance issue if they are not updated or reviewed over time.

Inexperience

Less experienced developers may not yet understand best practices for commenting and documentation. Consequently, their comments can lack professionalism or clarity, leading to potential misunderstandings or bugs down the line. As developers gain more experience, they often develop a stronger sense of professional coding practices.

Personal Style

Some developers have a more casual or irreverent style that reflects their personality. This personal style can come through in their comments, making the code more conversational and easier to read for those familiar with the developer's work. However, this style may not be appropriate for all contexts, especially in more formal or professional settings.

Case Study: Unprofessional Comments in Action

Consider a comment from years ago that read, "because google chrome is fucked up." This type of comment, while intended to express frustration, can be problematic in a professional setting. It raises questions about how such comments make it past code reviews. While the comment may have been a fleeting expression of frustration, it can leave a lasting negative impact on the codebase.

Proving the Point

Another example might be a comment that reads, "This system was built by a lone developer." Such comments can be seen as defensive or as a way to shift blame, rather than providing useful information. It’s important to maintain a level of professionalism to ensure that the code is easily understandable and maintainable.

Conclusion

While unprofessional comments can sometimes add character or humor, they can also lead to misunderstandings and a lack of clarity. It is generally advisable to maintain a professional tone in code comments to ensure easy understanding and maintainability. Ensuring that code comments are clear, concise, and professional is key to the longevity and effectiveness of the code.
