How can I use the rest operator in JavaScript classes?

The rest operator allows you to collect all remaining elements into an array. In classes, you can use it in methods to handle variable numbers of arguments.

Can you show me an example of using the rest operator in a class method?

Sure! Here's a simple example:

class MyClass {
    myMethod(...args) {
        console.log(args);
    }
}

const instance = new MyClass();
instance.myMethod(1, 2, 3); // Output: [1, 2, 3]

What if I want to combine the rest operator with other parameters?

You can mix regular parameters with the rest operator. For example:

class MyClass {
    myMethod(first, ...rest) {
        console.log(first, rest);
    }
}

const instance = new MyClass();
instance.myMethod(1, 2, 3, 4); // Output: 1 [2, 3, 4]
