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

Some common mistakes include using the rest operator in the wrong context, such as 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 that doesn't accept any parameters, like this: function test() { const args = ...rest; }.

What about using it with destructuring?

When destructuring, a mistake is trying to use the rest operator in the wrong position, like const { a, ...rest, b } = obj; which will throw an error.

How can I avoid these mistakes?

To avoid these mistakes, always ensure you're using the rest operator in the correct context and position, and test your code with various inputs.
