What are the best practices for gradual typing in programming?

Gradual typing allows you to introduce types incrementally. Key practices include starting with dynamic types, then adding type annotations as needed.

Can you give me an example of how to implement gradual typing?

Sure! Start with a dynamically typed function, then gradually add type hints. For instance, in Python, you can start with def add(a, b): return a + b and later change it to def add(a: int, b: int) -> int:.

What are the benefits of using gradual typing?

Benefits include improved code readability, easier debugging, and the ability to catch type-related errors early without losing the flexibility of dynamic typing.

Are there any tools that can help with gradual typing?

Yes, tools like MyPy for Python and TypeScript for JavaScript can help enforce type checks while allowing gradual typing.
