Keep comments useful, not noisy
What comments do
Comments are notes inside source code that are ignored by the compiler or interpreter. They can explain intent, constraints, or tradeoffs when the code alone is not enough.
Most languages use line comments for short notes and block comments for larger spans.
Why comment clutter hurts
Too many comments slow down scanning. Redundant notes, outdated explanations, and commented-out code make it harder to see what still matters.
The bigger the codebase, the more expensive stale comments become.
What good comments look like
Useful comments explain why something exists, what constraint it respects, or which edge case it protects.
Weak comments restate obvious code or drift out of sync with the implementation.
How CommentClean helps
CommentClean strips comment noise so you can inspect logic, refactor, or share a cleaner snippet quickly.
If a comment is still valuable, you can always add it back with better wording and fresher context.
