Contact form using Tailwind, Parcel and Vanilla JS

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

Form validation! It was my first time working with setTimeout and writing more maintanable code in JS using pure functions. I would do more form validation next time!

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

Setting a duration of time before the toast is hidden. setTimeout() really helped with this!

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

JS code. Is there any way I could make the functions more concise, shorter, and cleaner? Any tips and suggestions on the JS code are welcome (especially maintanability)
