Are variadic functions type-safe?

Can you explain what variadic functions are?

Sure! Variadic functions are functions that can accept a variable number of arguments. For example, in C, the printf function can take any number of arguments.

Are variadic functions type-safe?

It depends on the programming language. In languages like C, they are not type-safe because the types of arguments are not checked at compile time.

What are the risks of using variadic functions?

The main risks include type mismatches and potential runtime errors, as the function may not handle unexpected argument types properly.

Can you give an example of a type-safe variadic function?

In languages like TypeScript, you can create type-safe variadic functions using rest parameters with specific types, ensuring type safety.
