Age calculator app - Html Css (Sass) Js

hello everyone ;) this challenge was not very simple, from the point of view of the implementation of the JS code, as I had to do several tests until I got to cover all the various types of possible errors by the user and related error messages.

Figuring out how to calculate age taking into account all possible variables, including whether or not the year is a leap year, also got me busy. But precisely for this reason it was a very useful challenge for the continuous learning of JS.

How do you think he solved the challenge? if you have any question/information/suggestion I'm here and we can discuss it..see you next time ;)
