What are some common errors when using the rest operator in JavaScript?

Some common errors include using the rest operator in the wrong context, like trying to use it in a non-iterable situation.

Can you give me an example of using the rest operator incorrectly?

Sure! A common mistake is trying to use the rest operator in a function parameter without defining it correctly, like this: function myFunc(...args, extra) {}.

What happens if I do that?

It will throw a syntax error because the rest parameter must be the last parameter in the function definition.

Are there any other common mistakes I should be aware of?

Yes, another mistake is trying to use the rest operator with non-iterable objects, which will also result in an error.
