What are the best practices for using optional types in programming?

Using optional types can enhance code safety and clarity. It's best to use them when a value may or may not be present.

Can you give me an example of when to use optional types?

Sure! Use optional types for function parameters that are not always required, like a user profile update where some fields may be omitted.

What are the risks of not using optional types?

Not using optional types can lead to null reference errors, making your code less robust and harder to maintain.

How do optional types differ from nullable types?

Optional types explicitly indicate that a value may be absent, while nullable types allow a variable to hold a null value.

Are there any performance implications of using optional types?

Generally, the performance impact is minimal, but it's good to be mindful of how they are used in performance-critical code.
