// This is a single-line comment

This is a multi-line comment.
It can span across multiple lines.
Multi-line comments are helpful when you need to provide more detailed explanations or comment out a block of code temporarily.
Commenting Best Practices
While adding comments can be beneficial, it’s important to follow some best practices to ensure their effectiveness:
1. Be Concise: Keep your comments short and to the point. Long comments can be overwhelming and may distract from the code itself.
2. Use Proper Grammar and Spelling: Ensure that your comments are grammatically correct and free of spelling errors. This helps maintain professionalism and readability.
3. Explain the Why, Not the What: Instead of explaining what the code does (which should be evident from the code itself), focus on explaining why the code is written in a particular way. This provides valuable insights for other developers.
4. Update Comments Regularly: Code evolves over time, and comments can become outdated. Make sure to review and update your comments whenever you make significant changes to the code.
