Where the JavaScript Comment Remover helps in real life

A developer embeds a small script inline in a page and wants it shorter without a full build tool.
Common mistakes to avoid
- Removing license comments that must stay with the code.
- Expecting it to minify or rename variables.
- Running it on code with syntax errors.
- Deleting comments that explain tricky logic in your source files.
💡 Practical tip: Keep comments in your source code — strip them only from copies you share or embed.

Tips for better results
- Keep the commented original as your source of truth.
