so when you use 'delete' it only deletes the output for calls to it after? but the actual object does not change?

[@barbarasanchezvasquez2242]

Thanks. Could you please tell me why would I want to delete a property from an object?

[@gaganbedi4332]

case: someone wants to delete his bio from instagram.

Why is it that the object in Javascript is not derived from class unlike other programming languages? Is it because it's too cool for school? 😅😅
