I used HTML , CSS and JavaScript for age calculation and display

During the development of my age calculator app using HTML, CSS, and JS, I faced several challenges. One of the difficulties I encountered was validating user input to ensure that the date of birth was entered correctly. Another challenge was calculating the correct age based on the current date. As for areas of my code that I am unsure of, I found the code that handles date calculations to be a bit complex and challenging to understand. However, I was able to address this by seeking feedback from other developers and refactoring the code. Regarding best practices, I made sure that my code was clean and well-organized, optimized for performance and speed, and followed established security and data privacy guidelines.
