In the above code, the calculateAge function takes a birthdate string in the format ‘YYYY-MM-DD’ as input. It creates Date objects for the current date and the birthdate. The age is then calculated by subtracting the birth year from the current year. If the current month is before the birth month, or if it’s the same month but the current day is before the birth day, we subtract 1 from the age because the person hasn’t had their birthday yet in the current year.
Note that the code assumes the birthdate is in the ‘YYYY-MM-DD’ format. If your birthdate is in a different format, you may need to modify the code accordingly.
