How do I define variadic functions in programming?

What are variadic functions and how do I define them?

Variadic functions are functions that can take a variable number of arguments. In languages like C, you define them using an ellipsis (...) in the function parameters.

Can you give me an example in Python?

Sure! In Python, you can define a variadic function using *args. For example:

def my_function(*args):
    for arg in args:
        print(arg)

What about in JavaScript?

In JavaScript, you can use the rest parameter syntax. Here's an example:

function myFunction(...args) {
    args.forEach(arg => console.log(arg));
}

Are there any limitations to variadic functions?

Yes, variadic functions can make code harder to read and debug. It's important to handle the arguments carefully to avoid errors.
