The answer is A) 'object'. I remember learning that in JavaScript, null is considered an object type, even though it's a primitive value. Weird language, but that's just how it is.

Haha, JavaScript, where null is an object. That's like saying an empty glass is a type of glass. Gotta love it!

Wait, what? 'object' for null? That's weird. I would have guessed 'null'.

I think the correct answer is 'object'. Even though null is a primitive value, the typeof operator returns 'object' for null in JavaScript.

The output should be 'object' because null is a special value in JavaScript that represents the intentional absence of any object value.
