Commenting is the practice of adding notes or remarks to a piece of text, code, or other content. It is commonly used in programming to explain what specific sections of code do, making it easier for others (or the original author) to understand the logic behind it. Comments are typically not executed as part of the program, allowing developers to provide context without affecting functionality. In online platforms, commenting allows users to share their thoughts or feedback on articles, videos, or social media posts. This interaction fosters community engagement and can lead to discussions among users. Comments can also help creators understand their audience's opinions and improve their content.
