What are the differences between type annotations and dynamic typing?
An example of an AI chatbot conversation about type annotations vs dynamic typing.
What are the differences between type annotations and dynamic typing?
Type annotations are explicit declarations of variable types, while dynamic typing allows types to be determined at runtime.
Can you give me an example of type annotations in Python?
Sure! In Python, you can use type annotations like this: def add(a: int, b: int) -> int: which specifies that both parameters and the return type are integers.
What are the advantages of using type annotations?
Type annotations can improve code readability, help with static type checking, and make it easier to catch errors during development.
How does dynamic typing work in languages like JavaScript?
In JavaScript, variables can hold any type of data, and their type can change at runtime, allowing for more flexibility but also potential runtime errors.
