what is the meaning of:AsNan() in java script?

Question

what is the main objective?

Answer 1

I never heard about AsNan() maybe you wanna know about isNaN() , first of all , The NaN property represents "Not-a-Number" value. This property indicates that a value is not a legal number. The NaN property is the same as the Number. So isNaN() checks that it will give a NaN [ Generally Caused by Maths Error ] or not.
