Newsletter Sign up Form using JS and Sass

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

I'm understanding more native JS. I manage well React but is always good to do exercises in native language to improve skills.

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

how to show another page when i clicked a submit btn. In react is easy with routes, but not in JS for me. Thanks for CHAT-GPT for teach me how i can use window interface.
