What steps do you take to ensure your code is free of errors before submitting it for review?

1. Understand the Requirements: Before you start coding, make sure you fully understand what the code is supposed to do. This will help you avoid logical errors.

2. Plan Your Code: Before you start coding, plan out your code. This can help you spot potential issues before they become problems.

3. Code in Small Chunks: Don't try to write all your code at once. Instead, write a small piece, test it, and then move on to the next piece. This makes it easier to spot and fix errors.

4. Use a Linter: A linter is a tool that checks your code for syntax errors and other common mistakes. Use one to catch errors before they cause problems.

5. Test Your Code: After you've written your code, test it to make sure it works as expected. This can help you catch any errors that you might have missed.

6. Code Review: Have someone else review your code. They might spot errors that you missed.

7. Use Version Control Systems: Version control systems like Git can help you keep track of changes and spot errors.

8. Continuous Integration: Use continuous integration tools to automatically build and test your code whenever you make changes. This can help you catch errors quickly.

9. Automated Testing: Use automated testing tools to test your code. This can help you catch errors that you might not have thought to test for.

10. Code Refactoring: Regularly review and clean up your code to make it easier to understand and maintain. This can help you spot and fix errors.

By following these steps, you can significantly reduce the number of errors in your code before it goes for review.
