What are the differences between type hinting and dynamic typing?

Type hinting is a feature in some programming languages that allows you to specify the expected data type of a variable, while dynamic typing means that the type of a variable is determined at runtime.

Can you give me an example of type hinting?

Sure! In Python, you can use type hints like this: def add(a: int, b: int) -> int: which indicates that both a and b should be integers and the function returns an integer.

What about dynamic typing? How does it work?

In dynamically typed languages like JavaScript, you can assign any type of value to a variable without declaring its type. For example, let x = 5; x = 'Hello'; is perfectly valid.

Which one is better to use?

It depends on the context! Type hinting can help catch errors early and improve code readability, while dynamic typing offers more flexibility and ease of use.
