What I learned

This project was a huge challenge for me, and not for quite the right reasons. I learned a lot about proper planning for a project, and considering the architecture more thoughtfully ahead of time. This project really shouldn't have been very complicated, and yet my lack of planning and forethought made it quite the challenge.

In my defense, I tried to create a more robust system that is dynamically expandable. You should be able to add more quizzes and questions to each quiz, and the code should take care of the rest in generating the questions and everything for you.

Continued development

I feel as though both my CSS and JavaScript are overly complicated for this project. I ended up throwing in all kinds of things into my CSS to account for edge cases, while I probably could have simplified the logic for a lot of this had I been more thoughtful.

Same thing with my JavaScript. In fact, the final product is much simpler than what I had midway through the project. I did quite a bit of refactoring that slimmed down the logic a bit here.

Overall, in the future, I will take more careful consideration of my projects, and probably write out an outline or draft in pseudo code to attempt to make things easier.
