Plain Text Comments
Plain text comments are annotations written in human-readable language within source code to explain its purpose, logic, or functionality, without being executed by the computer. They serve as documentation for developers to understand, maintain, and collaborate on code, and are typically ignored by compilers or interpreters during execution. This concept is fundamental across all programming languages and development environments.
Developers should use plain text comments to improve code readability, facilitate team collaboration, and aid in debugging and future maintenance, especially in complex projects or when working with legacy code. They are essential for documenting assumptions, explaining non-obvious logic, and providing context that isn't apparent from the code itself, such as in algorithms, business rules, or workarounds.
