Age calculator with React, tailwindcss and day.js date library

What are you most proud of, and what would you do differently next time?

The most useful step I made was to research for Date related libraries or packages that simplifies the process of validating user date and I'm happy with that.

I was able to validate user input by using day.js isValid method that requires a date and date format and it automatically parse it and checks for validation.

What challenges did you encounter, and how did you overcome them?

It was challenging to detect month and day cycle and implement the logic of adding or subtracting month difference.

I solved by having multiple if else conditions that checks if birth month is before or ahead of current month to add or subtract and otherwise not adding if month difference is zero.

What specific areas of your project would you like help with?

I would like to hear your feedback on my age calculation approach and any other feedback will be gladly appreciated. Thanks!
