Global Commenting

Strategic commenting focuses on explaining complex logic and non-obvious decisions rather than restating what the code does. Write comments that capture the 'why' and 'intent' behind code, then refactor unclear sections to be self-documenting through better naming and structure, keeping comments minimal and high-value.

Add comments only where logic is genuinely complex or reasoning is non-obvious; otherwise, prioritize self-documenting code through clear naming, structure, and straightforward implementation. Comments should explain intent and constraints, not restate what readable code already shows.

Review comments for relevance and necessity: remove those restating obvious code, consolidate redundant explanations, and preserve only comments explaining complex algorithms, non-standard decisions, or critical reasoning. This audit reduces maintenance burden and improves code clarity.

Yes, commenting principles apply universally across languages and file types including PHP, JavaScript, TypeScript, and Vue. Self-documenting code and strategic comments for complex logic remain effective regardless of syntax or framework.

Helpful comments explain non-obvious intent, architectural decisions, and complex reasoning; unhelpful ones restate code behavior or become outdated as logic changes. Technical debt comments are maintenance liabilities; focus instead on clear naming and structure that reduce comment dependence.
