How do I use arguments in JavaScript?

In JavaScript, arguments are values passed to functions when they are called. You can access them using the 'arguments' object.

Can you give me an example of a function that uses arguments?

Sure! Here's a simple example:

function add(a, b) {
    return a + b;
}

console.log(add(5, 3)); // Outputs: 8

What if I want to use a variable number of arguments?

You can use the rest parameter syntax. For example:

function sum(...numbers) {
    return numbers.reduce((acc, curr) => acc + curr, 0);
}

console.log(sum(1, 2, 3, 4)); // Outputs: 10

Are there any limitations to using arguments?

Yes, the 'arguments' object is not available in arrow functions, and it does not have array methods. It's better to use rest parameters for modern JavaScript.
