How do I use the arguments object in JavaScript?

The arguments object is an array-like object available within functions that contains the values of the arguments passed to that function. You can access it using arguments[index].

Can you give me an example of how to use it?

Sure! Here's a simple example:

function sum() {
    let total = 0;
    for (let i = 0; i < arguments.length; i++) {
        total += arguments[i];
    }
    return total;
}

console.log(sum(1, 2, 3)); // Output: 6

Is the arguments object the same as the rest parameter?

No, they are different. The arguments object is not an actual array, while the rest parameter syntax (...args) allows you to create a real array from the remaining arguments.
