Duck Typing vs Explicit Functions

Developers should learn duck typing when working in dynamically-typed languages to write more generic and reusable code that focuses on what objects can do rather than what they are meets developers should use explicit functions to enhance code readability, facilitate debugging, and support type safety in statically-typed languages like typescript or java. Here's our take.

Duck Typing

Nice Pick

Developers should learn duck typing when working in dynamically-typed languages to write more generic and reusable code that focuses on what objects can do rather than what they are

Pros

• It's particularly useful for creating flexible APIs, implementing design patterns like strategy or adapter, and handling diverse data structures in a uniform way, such as iterating over collections regardless of their specific type
• Related to: dynamic-typing, polymorphism

Cons

• Specific tradeoffs depend on your use case

Explicit Functions

Developers should use explicit functions to enhance code readability, facilitate debugging, and support type safety in statically-typed languages like TypeScript or Java

Pros

• They are particularly valuable in large codebases, team collaborations, and when building APIs where clear contracts between components are essential to prevent errors and misunderstandings
• Related to: type-annotations, function-signatures

Cons

• Specific tradeoffs depend on your use case

The Verdict

Use Duck Typing if: You want it's particularly useful for creating flexible apis, implementing design patterns like strategy or adapter, and handling diverse data structures in a uniform way, such as iterating over collections regardless of their specific type and can live with specific tradeoffs depend on your use case.

Use Explicit Functions if: You prioritize they are particularly valuable in large codebases, team collaborations, and when building apis where clear contracts between components are essential to prevent errors and misunderstandings over what Duck Typing offers.

The Bottom Line

Duck Typing wins

Developers should learn duck typing when working in dynamically-typed languages to write more generic and reusable code that focuses on what objects can do rather than what they are
