Question

What will happen if we call isNAN function on “seventy-eight” and 78?

A. It will return false for both “seventy-eight” and 78 because both are numbers.

B. It will return true for “seventy-eight” and 78 because “seventy-eight” is a string and 78 is a number.

C. It will return false for “seventy-eight” and true for 78 because “seventy-eight” is easy to read and 78 is not.

D. It will return false for both “seventy-eight” and 78 because JavaScript will treat “seventy-eight” and 78 the same though auto conversion.

As we know isNaN() function will return true if the value is not a number else it returns false.

As 78 is number so it returns false and seventy eight is string so it returns true .
