Answer 1

Answer:

The Number() function converts the object argument to a number that represents the object's value. If the value cannot be converted to a legal number, NaN is returned. Note: If the parameter is a Date object, the Number() function returns the number of milliseconds since midnight January 1, 1970 UTC.
