Responsive Age-calculator website made with HTML, CSS, REACT

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

Great work with javascript after a while. This App can calculate your age and detect any wrong date that you enter and it gives you specific errors (including recognizing the ability of the leap year and observing its days).

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

I made a condition for one of my components that made me go through a challenge but I passed it and learned from it.
