In programming, what role does a 'comment' serve?

In programming, a comment serves the important purpose of providing explanations or notes within the code. Comments are non-executable lines that developers use to clarify what specific sections of code do, making it easier for others (or themselves at a later time) to understand the logic and intent behind the code. This is especially useful in collaborative environments where multiple people might work on the same codebase. Comments help to document the thought process, outline steps, and provide context that can clarify complex or non-obvious logic.

The role of comments enhances maintainability and readability of code, as well-commented code can significantly reduce the time needed for someone to grasp the functionality of the script. Comments can also help in debugging processes by allowing developers to isolate segments of code by commenting them out without removing them entirely from the script. Overall, the inclusion of comments is a best practice in programming that facilitates clearer communication through code.
