Commenting Best Practices
1. Be Clear and Concise: Write comments that are easy to understand and provide relevant information about the code. Avoid unnecessary comments that state the obvious.
2. Use Proper Grammar and Spelling: Maintain good writing practices by using correct grammar, punctuation, and spelling in your comments. This helps other developers who may read your code.
3. Update Comments Regularly: Comments should be kept up to date with the code. If you make changes to the code, remember to update the corresponding comments to reflect those changes.
4. Avoid Commenting Out Code: Instead of commenting out lines of code, consider using version control systems like Git to manage code revisions. Commented-out code can clutter the codebase and make it harder to understand.
