Responsive signup form with input validation

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

Recently started learning typescript so wanted to practise it with this challenge. For styling, used a different CSS framework this time - Tailwind CSS. Lastly used the testing library to add some tests to the signup form input validation logic.

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

I struggled a bit in the start to get the right typescript and tailwind configurations to get the project to run correctly. Reading the following links helped tsconfig documentation and Tailwind CSS with create react app .

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

I would appreciate any feedback/recommendation on how I have implemented the tests for the input validation logic. Thanks!
