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

I'm proud of the improvement I've had with logical problems and that I could implement Object Oriented methodology I've been studying for the past few weeks.

I've also learned a few cool tricks on sass. Guess next time I would try to do things a little bit cleaner, I also think this project is not as scalable as I'l like it to be, so next time I'll try thinking out of the box, not only the specifics of the project of today, but things it might need tomorrow.

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

I've experienced a few problems with handling events, like when I show the errors, sometimes it would still popup after the user's input is bigger than 0, but I've managed to deal with it studying a little bit more about how events like keydown and keyup work.

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

Any feedback is welcome.
