Gradual Typing vs Duck Typing
Developers should learn gradual typing when working on large, evolving codebases where full static typing might be too restrictive or costly to adopt all at once meets 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. Here's our take.
Gradual Typing
Developers should learn gradual typing when working on large, evolving codebases where full static typing might be too restrictive or costly to adopt all at once
Gradual Typing
Nice PickDevelopers should learn gradual typing when working on large, evolving codebases where full static typing might be too restrictive or costly to adopt all at once
Pros
- +It is particularly useful in projects transitioning from dynamic to static typing, as it allows teams to add type annotations incrementally to improve code reliability, catch errors early, and enhance tooling support like autocompletion
- +Related to: type-systems, static-typing
Cons
- -Specific tradeoffs depend on your use case
Duck Typing
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
The Verdict
Use Gradual Typing if: You want it is particularly useful in projects transitioning from dynamic to static typing, as it allows teams to add type annotations incrementally to improve code reliability, catch errors early, and enhance tooling support like autocompletion and can live with specific tradeoffs depend on your use case.
Use Duck Typing if: You prioritize 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 over what Gradual Typing offers.
