В этот кластер входят материалы о предназначении и стратегиях написания комментариев к программному коду для обеспечения его сопровождаемости.
Общие признаки: необходимость внешнего документирования, различие между 'как' и 'почему', поддержка и обслуживание кода, самодокументированный код
Группа выше: Техническая документация: практика и автоматизация
Смысл: The main idea is that while clean, self-documenting code is the ideal, comments are still necessary to explain the 'why' behind complex logic and non-obvious implementation choices.
While clean code reduces the need for comments, they remain essential for explaining the reasoning behind complex logic and preventing future confusion.
Смысл: The main idea is that 'self-documenting code' is an insufficient goal because code describes *how* something is done, whereas documentation explains *why* and *what* is happening, making external documentation and comments essential for long-term maintainability and collaboration.
Self-documenting code is a myth because programming syntax and complex application logic are inherently unintuitive, necessitating the use of external documentation, diagrams, and comments.
Смысл: The main idea is that code comments are a critical tool for collaboration and maintenance, and there are specific strategic approaches to writing them—both during initial development and when documenting legacy code—to ensure clarity without adding noise.
Effective code commenting involves planning logic via comments before coding and using a top-down approach for legacy systems while avoiding redundant or defeatist remarks.
