What are the best practices for using variadic functions?

When using variadic functions, it's important to ensure type safety, validate inputs, and document the function clearly.

Can you explain why type safety is important?

Type safety helps prevent runtime errors by ensuring that the arguments passed to the function are of the expected types.

What are some common pitfalls to avoid?

Common pitfalls include not checking the number of arguments, assuming all arguments are of the same type, and not handling edge cases.

How can I document a variadic function effectively?

You can document a variadic function by clearly stating the expected types of arguments, providing examples, and explaining the behavior with different inputs.
