Frontend Mentor - Age calculator app solution

Hi everybody! 👋

This is a solution to the Age calculator app challenge on Frontend Mentor.

• PS: I don’t quite understand how to animate the transition of numbers (bonus of the challenge), if anyone could guide me at this point I would thank them.
• PS2: if someone wanted to check my javascript code and suggest how to improve it would be great. Saludos!

The challenge 🎯

Users should be able to:

• View an age in years, months, and days after submitting a valid date through the form
• Receive validation errors if:
  • Any field is empty when the form is submitted
  • The day number is not between 1-31
  • The month number is not between 1-12
  • The year is in the future
  • The date is invalid e.g. 31/04/1991 (there are 30 days in April)
• View the optimal layout for the interface depending on their device's screen size
• See hover and focus states for all interactive elements on the page
• Bonus: See the age numbers animate to their final number when the form is submitted

What I learned 📚

This work was a real challenge when testing my skills with javascript, mainly when I had to create the functionalities of error messages for inputs and also to assemble the age calculation. With this challenge I began to get into the management of functions and calculations.

Continued development 🔨

In the following challenges I want to improve my javascript skills. I must strengthen my knowledge and management of functions, field validation and much more.
