Debugging and Problem Solving

Error Analysis

Get help understanding and fixing errors in your code:

Debugging Approaches:

Error explanation:

> I'm getting this error: [paste error message]. What does it mean and how can I fix it?

Logic debugging:

> This function isn't working as expected. Can you help me identify the issue?

Performance issues:

> My application is running slowly. What could be causing performance bottlenecks?

Testing and Validation

Generate tests and validate your code implementations:

Testing Examples:

Unit test generation:

> Generate unit tests for this function.

Test case scenarios:

> What edge cases should I test for this user input validation?

Integration testing:

> Help me write integration tests for this API endpoint.

Documentation and Code Comments

Automated Documentation

Generate comprehensive documentation and comments for your code:

Documentation Tasks:

Function documentation:

> Add comprehensive JSDoc comments to this function.

README generation:

> Create a README file for this project with installation and usage instructions.

API documentation:

> Generate API documentation for these endpoints.

Best Practices for AI-Assisted Development

✅ Effective Practices

  • Provide clear context about your project and goals
  • Break complex tasks into smaller, manageable steps
  • Review and test all AI-generated code
  • Ask for explanations of suggested solutions
  • Iterate and refine based on feedback

⚠️ Important Considerations

  • Always validate AI-generated code before deployment
  • Understand the code rather than blindly copying
  • Consider security implications of suggested solutions
  • Test edge cases and error scenarios
  • Maintain coding standards and project conventions
