Coding Best Practices
Follow these guidelines during the practical coding section to maximize your score.
Write Clean, Readable Code
- Use meaningful variable and function names
- Keep functions small and focused on a single task
- Follow consistent formatting and indentation
- Add comments for complex logic, not obvious code
Handle Errors Gracefully
- Use try-catch blocks for error-prone operations
- Provide meaningful error messages
- Fail fast and fail loudly in development
- Log errors with context for debugging
Optimize for Performance
- Understand time and space complexity
- Avoid premature optimization
- Use appropriate data structures
- Consider caching for expensive operations
Write Testable Code
- Separate concerns (business logic vs I/O)
- Use dependency injection
- Keep functions pure when possible
- Test edge cases and error paths
