Default Parameters vs Optional Objects

Developers should use default parameters to write cleaner, more robust code by handling missing inputs gracefully without verbose conditional logic meets developers should use optional objects when dealing with functions or data that might return null or have no valid result, such as database queries, api responses, or configuration lookups. Here's our take.

Default Parameters

Nice Pick

Developers should use default parameters to write cleaner, more robust code by handling missing inputs gracefully without verbose conditional logic

Pros

• This is particularly useful in functions with optional arguments, such as configuration settings, API calls with optional parameters, or utility functions where sensible defaults exist
• Related to: function-definition, parameter-handling

Cons

• Specific tradeoffs depend on your use case

Optional Objects

Developers should use optional objects when dealing with functions or data that might return null or have no valid result, such as database queries, API responses, or configuration lookups

Pros

• They are particularly valuable in statically-typed languages to enforce compile-time checks for null safety, reducing runtime errors and improving maintainability in systems where missing values are common
• Related to: null-safety, functional-programming

Cons

• Specific tradeoffs depend on your use case

The Verdict

Use Default Parameters if: You want this is particularly useful in functions with optional arguments, such as configuration settings, api calls with optional parameters, or utility functions where sensible defaults exist and can live with specific tradeoffs depend on your use case.

Use Optional Objects if: You prioritize they are particularly valuable in statically-typed languages to enforce compile-time checks for null safety, reducing runtime errors and improving maintainability in systems where missing values are common over what Default Parameters offers.

The Bottom Line

Default Parameters wins

Developers should use default parameters to write cleaner, more robust code by handling missing inputs gracefully without verbose conditional logic
